The Hewlett-Packard Company (NYSE: HPQ), commonly referred to as HP, is a technology corporation headquartered in Palo Alto, California, United States. HP is the largest technology company in the world and operates in nearly every country.

HP's Officejet 6000 Wireless is an inexpensive four-color ink-jet printer that, as its name implies, has wireless 802.11b/g connectivity. It also has an inexpensive price per print--as long as you buy HP's high capacity ink tanks. Though office ink-jets are nothing new, HP positions the Officejet 6000 as a greener and cheaper alternative to workplace color laser printers.

Setting up the printer isn't difficult but required a few more steps than with most ink-jet printers. The Officejet 6000 uses a print head that's separate from the ink cartridges, and you must open and install the print head before inserting the ink cartridges. You also have to attach the duplexing unit to the back of the printer.

The printer's design is simple and stylish, with rounded corners and a mix of light and dark gray plastic. There are four small buttons on the front, a Power button, a Print Cancel button, a Paper Feed button, and a Wi-Fi button allowing you turn off the wireless capabilities when not in use (a non-Wi-Fi version of the Officejet 6000 is available for US$30 less). The Officejet 6000 has a 250-sheet paper feed and a 50-sheet output tray. It can print automatically on both sides of a sheet of paper, which can help save both trees and money.

Your three options for connecting to the Officejet 6000 are Wi-Fi, USB 2.0 and Ethernet. The Wi-Fi setup was easy; in my experience, some printers make you struggle with the on-printer menus and keys to type in passwords, but the Officejet 6000 lacks such controls. You need to setup the wireless connection from your Mac during the driver installation from the bundled software CD. Once the printer was configured for our wireless network, it showed up automatically in Bonjour when installing the drivers on other systems.

Image quality

The Officejet 6000's print quality was impressive. During our jury evaluation, the text output received a Very Good rating and could truly be compared to laser quality. Many ink-jets struggle with printing clean text on plain paper; as the ink is absorbed into the paper, it can spread and look messy and fuzzy. Our jury found it difficult to notice any ink bleed or fuzziness with text.

Photos printed on HP's Advanced Glossy Photo Paper also received a Very Good rating. Colors were bright and pleasing, though the output wouldn't compare favorably to a high-end photo printer as it lost much detail in the darker areas of the print. It looks much better than a photo printed on a laser printer with glossy laser paper, however.

Photos and graphics on plain paper weren't of the same high quality, unfortunately, with colors appearing light and muted. Prints using HP's Colorlok Multipurpose paper looked better than prints made on our office copier paper, but there were still some banding in the color ramps of our test page and a blue cast to a grayscale photo we printed. The fine and curved lines looked great.

Cost

With printer reviews, we're constantly asked about the cost to run and maintain a device. If you buy HP's high capacity inks, the four cartridges will cost about $77, which, when divided by the company's estimated ink yields, breaks down to about $.03 per page (black only) and $.09 per page (color). That is a cheaper cost per color page than the last four sub-$1,000 color laser printers we reviewed, and the cost per monochrome page is pretty close to those laser costs.

If you opt for the lower priced, lower capacity inks, the cost per black page increases to $.05 (black) and a full color page will cost $.15. For comparison's sake, another office-oriented ink-jet, Epson's WorkForce 600 ( Macworld rated 4 out of 5 mice ), costs $.04 per page (black) and $.14 per full color page when using high capacity ink cartridges. Prints using HP's standard capacity ink cartridges cost just over $.07 per page (black) and over $.19 per full color page.

Speed

In terms of speed, the Officejet 6000 was an average performer. Over USB, its 15-second first page out time was fast. The Officejet 6000 printed a 10-page Word document in 1 minute, 15 seconds, and our 4-page PDF in 1 minute, 12 seconds. It took a while longer to print our 22MB color photo in Photoshop, clocking in at 2 minutes, 36 seconds.

Print times increased a bit when printing over our office wireless network. One thing I should mention is that the printer makes some interesting noises after each job, leading you to think, perhaps, that another sheet is about to exit the printer. It's not a big deal, but could be a little annoying if the printer is sitting on your desk next to you.

Macworld buying advice

If you're in the market for a lower-priced, more environmentally friendly printer for your small business, an ink-jet like HP's Officejet 6000 Wireless may be a better fit than a laser printer. Its smaller, uses less energy, has a low price per print and great looking text. The OfficeJet 6000 can also produce better-looking photos on glossy stock than laser printers typically can.

PRINTERS MAINTENANCE & CLEAN TIPS

noreply@blogger.com (Tegap Jitu Enterprise) — Wed, 27 May 2009 15:57:00 +0000

In computing, a printer is a peripheral which produces a hard copy (permanent human-readable text and/or graphics) of documents stored in electronic form, usually on physical print media such as paper or transparencies. Many printers are primarily used as local peripherals, and are attached by a printer cable or, in most newer printers, a USB cable to a computer which serves as a document source. Some printers, commonly known as network printers, have built-in network interfaces (typically wireless or Ethernet), and can serve as a hardcopy device for any user on the network. Individual printers are often designed to support both local and network connected users at the same time.

Printers require a little more maintenance than other peripheral devices. They have several different parts working together at once, which means it's easy for one or more of the parts to jam and cause performance problems. Cleaning your printer regularly will help prevent these complications.

Every printer is different of course, so the cleaning and maintenance process may vary just a bit. But for the most part, there are a few steps you can take that will help prolong the life of your machine-regardless of the type of printer you have.

Preventative Care of Your Printer

It's a good idea to perform preventative maintenance on your printer as often as you can. One of the most important parts of your device that you must always keep clean is the print head. If a printer has not been used for quite some time, there's a greater chance of the print head becoming clogged with dried-up ink. Needless to say, this will have a significant impact on the quality of output, and it can even do permanent damage to the printer. You can easily avoid any blocking or obstruction by simply cleaning the print head on a regular basis. The best way to do this is with a dry cloth. Gently wipe down every possible surface you can reach-especially all the nooks and crannies on the inside of the printer. Tiny particles of dust and dirt have a tendency to find their way into every little crevice, so be as thorough as you can.

Nowadays, most printers come with an automatic utility program that can instruct the printer to do a self-cleaning process. If you run these cleaning cycles fairly often and wipe down the inside of your printer on a regular basis, you shouldn't encounter too many problems. On the other hand, printers that do not come with an automatic cleaning cycle require a bit more attention. In this case, you may want to consider purchasing a cleaning kit, which usually includes a tube of ammonia that you can lightly spray on the print head to get rid of crusted ink.

Manually Cleaning Your Printer

If you are experiencing printer jams or any sort of ink build up, you can clean the print head manually by performing the following steps:

1.) Remove the cartridge from the printer. Dip a cotton swab in rubbing alcohol or hot water, and gently wipe down the cartridge. This should soften up the dry, crusted ink.
2.) Then, soak the print head in hot water and leave it there over night.
3.) If the print head is still clogged after soaking it all night in water, let it soak in rubbing alcohol over night.
4.) After removing it from the water (or alcohol), wipe off the print head with a damp paper towel, and let it dry off carefully.
5.) When you put it back in the printer, try running the self-cleaning cycle again.

If your print head is still clogged, you can either buy a new cartridge or you can contact a service technician who can try to repair the damage.

SOLVING REPEATED PAPER JAMS

1. Check to see that paper is correctly loaded in the trays, and that all width guides are correctly set (not skewed).

2. Ensure that the paper tray is set for the size of paper installed and that the tray is not overloaded with paper.

3. Try turning over the stack of paper in the tray. If you are using letterhead paper, try printing from Tray 1.

4. Do not use previously printed paper or torn, worn, or irregular paper

5. Check the paper specifications. (If paper is outside of the recommended specifications, problems may occur.)

6. When duplexing, the printer rolls paper under Tray 3 and causes a jam. Pull Tray 3 out of the printer completely and remove any paper from under the tray. Insert Tray 3 back into the printer.

7. Printer may be dirty. Clean the inside of the printer with a dry, lint-free cloth.

8. Check that the correct paper size is installed.

9. Check that all damaged or jammed paper is removed by pulling it out of the printer.

Printers Tips: Keep the Output Flowing From Your Laser Printer

noreply@blogger.com (Tegap Jitu Enterprise) — Fri, 22 May 2009 17:13:00 +0000

A laser printer is a common type of computer printer that rapidly produces high quality text and graphics on plain paper. As with digital photocopiers and multifunction printers (MFPs), laser printers employ a xerographic printing process but differ from analog photocopiers in that the image is produced by the direct scanning of a laser beam across the printer's photoreceptor.

Personal laser printers combine the economy and print quality of their more expensive enterprise counterparts with the price of an inkjet. Personal lasers lack an IT department to keep them running, however. Here's how to solve problems that may plague your laser printer.

The Windows Printing Troubleshooter wizard focuses on basic problems, but it's well worth trying. In Windows XP, choose Start, Help and Support, type list of troubleshooters in the Search box, and press Enter. Click list of troubleshooters in the left pane, select the Printing troubleshooter from the list on the right, and follow the steps. In Windows 2000, click Start, Help, and choose Troubleshooting and Maintenance on the Contents tab. Select Windows 2000 troubleshooters, click Print in the list of troubleshooter wizards in the right pane, and follow the steps. To open the wizard in Windows Me, click Start, Help, type troubleshooter in the Search box, and click Go. In Windows 98, select Start, Help, Contents, Troubleshooting, Windows 98 Troubleshooters, Print, and follow the wizard.

Check the basics: If your printer is plugged in but doesn't power up, look at the fuse or circuit breaker on the surge suppressor that your printer is plugged into. Reseat both ends of the USB or parallel cable that connects your printer to the PC. Many laser printers have an online/offline control on the front panel that may have been bumped inadvertently.

Print a test page: Most printers can run a self-test if you hold down one or more buttons on the control panel while the unit powers up. If the test page looks good, then the problem lies with your data cable, PC, or software. If the printout doesn't look right, see the chart below for a list of common problems and solutions.

Get the latest: Install the newest driver and firmware for your printer. Both should be available from the maker's Web site. To install a new driver in Windows XP, select Start, Printers and Faxes and choose Add a Printer under Printer Tasks on the Explorer bar in the 'Printers and Faxes' window. In Windows 2000, Me, and 98, remove the printer's driver and reinstall it: Select Start, Settings, Printers to open the Printers window. Right-click the printer, select Delete (choose Yes if you're asked to verify the removal), open the Printers window again if it closed, double-click Add Printer, and complete the reinstall.

Stop jam sessions: Always remove any jammed paper by pulling it in its normal direction of motion through the printer. If your printer chronically jams, unplug it, let it cool down, remove its toner cartridge, and examine the interior for any debris that may impede paper movement.

Check your connections: If your printer uses a USB connection, open Device Manager and look for a red X or an exclamation mark in a yellow circle next to any of the USB device listings: In Windows XP, 2000, and Me, click Start, right-click My Computer, and select Properties, Hardware, Device Manager. In Windows 98, right-click My Computer and choose Properties, Device Manager. These icons can signify a problem with your printer's link to your PC. If your printer stops working when your system comes out of hibernate or suspend mode, double-click each root hub listed under USB, select Power Management, and uncheck 'Allow the computer to turn off this device to save power'. If you're using a USB hub, see whether connecting the printer directly to the USB port on the PC solves the problem.

How to Troubleshooting Laser Printers?

Be sure all dip switches are properly set for your configuration. Laser configuration is sometimes done by a control panel of buttons with an LED display that permits you to alter configuration memory. Be sure that the application being used is properly configured for the printer as set up.
Fuzzy laser output could mean you have a dirty corona wire or you are running out of toner. Horizontal lines or splotches indicate possible damaged or dirty print drums or rollers. Since some of these components are part of the cartridge, a useful quick fix is simply to change the cartridge.
If laser images seem disproportionately long or short, the drive motor may not be moving the paper through at the correct speed.
Failure of a laser printer to go on-line might be a communication interface problem. It could also indicate a faulty control panel. Try powering up the printer with the cable removed. If it now goes to "ONLINE" (or "READY"), suspect the cable or its connector.
If you are printing totally black pages, suspect a broken or fouled corona wire. If that is not the case, replace the toner cartridge.
If the print appears speckled, it is probably the fault of the primary corona grid which is part of the toner cartridge. Replace the toner cartridge.
If white streaks appear in your printing, shake the toner cartridge to insure an equal distribution of powder. If that doesn't work, clean the transfer corona assembly. Contamination on the assembly will prevent it from holding the electrical charge needed to attract toner from the drum.
A repetitive pattern of printing defects, such as an identical smudge every 2 inches may indicate a defective fusing roller. Try cleaning it according to your hardware vendor's instructions. If that does not work, you may need to replace the fusing roller assembly.

Konica Minolta - Magicolor 1650EN

noreply@blogger.com (Tegap Jitu Enterprise) — Thu, 21 May 2009 16:03:00 +0000

The Konica Minolta magicolor 1650EN is an inexpensive color laser printer that produces beautiful black text and vibrant color images, and offers reasonably priced (albeit low-capacity) ink cartridge replacements. One of the first network color laser printers to break the $400 mark, this is an affordable home-office printer.
With its compact, opaque plastic design, the 1650EN is one of the smallest color lasers we’ve reviewed. It’s also comparatively lighter than other leading color laser printers, but at 33 pounds it’s by no means portable.

Printing costs

On the surface, the 1650EN has economics on its side. It has the lowest price of any color laser printer we've encountered; as of press time, it bests its lowest priced competitors, the HP CP2025DN ( Macworld rated 4 out of 5 mice ) and Lexmark C544DN ( Macworld rated 4.5 out of 5 mice ), by about $150. And with that you get standard features such as USB 2.0, 10/100 Ethernet, and PostScript 3 emulation. It costs only $399 to replace the Konica 1650EN's toner cartridges (more than the price of the printer itself), while the cartridges for its closest competition, the HP CP2025DN, costs at least $486.

But lower prices can be misleading. The purchase prices of the 1650EN's black and color cartridges seem reasonable, because of their low capacities the printer carries a higher price per page than its competition. The black ink cartridge, for example, costs a mere $72, but it prints only 2,500 pages--less than half of competing printers' ink cartridge page yields. The $109 price tag for each cyan, magenta, and yellow toner cartridge is also comparatively cheap, but the 2,500-page count puts the price per page on the higher side--north of 15 cents per page. This means that the 1650EN is actually more expensive than its competitors to use if you have high-capacity printing needs. The Oki Data C6150dn ( Macworld rated 4.5 out of 5 mice ), for example, has a higher initial price tag, but it costs only 10.5 cents to print a color page.

Print yields are analogous to paper capacity with the 1650EN. The 200-page paper tray is on the small side and its inability to perform duplexing as a standard feature makes the 1650EN a poor fit for businesses with high-capacity printing requirements. You can purchase a hardware add-on for $139 to give the 1650EN duplexing abilities, but users who need it will likely also need a higher-capacity printer.

Performance

Unfortunately, the 1650EN is exceptionally slow. The 1650EN finished our 10-page Word test 32 percent more slowly than the Oki Data C6150dn, our current top product in this category. For offices with heavy black text printing requirements, printing 10 pages in 52 seconds is painfully slow. A single page took 26 seconds to print, which is more than twice as slow as the Oki Data C6150dn.

Color printing for the 1650EN was equally sluggish. While the top laser printers on the market took 30 to 60 seconds to print our 22MB Photoshop image, the 1650EN took a nonchalant 3 minutes and 50 seconds to print this same picture. The 1650EN finished the 4-page PDF test in 2 minutes and 30 seconds--a full two minutes behind the Oki C6150dn.

Despite its slothful speed, the printer does turn out high-quality documents. In our jury tests, the black text was judged to be of Superior quality, while our Photoshop image quality and Fine Lines and Gradients tests earned Very Good scores from our judges - though only after running an, as yet unreleased, firmware update we received from the company that fixed an error where certain graphic elements failed to print. Konica Minolta representatives say that the firmware update is undergoing final testing and will be available from their support Web site soon. In the meantime, owners of the 1650EN calling Konica Minolta's tech support with this issue will be offered the pre-release update.

Macworld's buying advice

The compact Konica Minolta magicolor 1650EN can be ideal for low-capacity printing in a home or small business setting. Though replacing the consumables is cheap, you'll do it often and will have to absorb a higher price per page. Businesses with high-capacity printing needs should be wary of this product, but home users who may never burn through thousands of pages may find the 1650EN more appealing. In a home setting, the 1650EN's comparatively slow printing speeds will be outweighed by the printer's strong color and black text printing quality. The market has been slow to produce a color laser printer economical enough for a home setting, and the 1650EN may just satisfy that niche.

HP Officejet Pro 8500 Multi-Function Printer

noreply@blogger.com (Tegap Jitu Enterprise) — Tue, 19 May 2009 15:42:00 +0000

Hewlett Packard has been in the thick of action over the past one month. News has been flowing in from the HP camp regarding the new tools, fresh tie-ups, and a huge of array of printers that have been introduced, most of them at the PMA at Las Vegas in the US. One of the latest additions into the HP family is the office printer, Officejet Pro 8500 and its subsidiaries. It's a multi-function printer that can scan, copy and fax along with basic document and graphical colour printing.

Printing technology is based on Scalable Printing technology and it outputs monochrome prints at 1200 X 1200 dpi and colour prints at 4800 X 1200 dpi. The printer comes with a 384MHz processor and 128 MB onboard memory.

Printing speed for monochrome and colour at normal mode is claimed at 19 pages per minute, and we know that the rates claimed are never close to actuals. However, first page out takes around 15 seconds, which is unusual for a non-laser printer. Recommended monthly printing volume at the max is stated as 1250 pages which lies in the unrealistic realm.

By default, the printer comes with a USB 2.0 port to hook onto standalone systems and an Ethernet port for network printing. PictBridge port is also available on it. Enhanced versions of this printer offer Wi-Fi support.

The basic version of HP Officejet Pro 8500 is priced at £150 while the Wi-Fi enabled model, HP Officejet Pro 8500 Wireless All-in-One carries a price tag of £200. The price is not an issue on this printer but its workability over a period of time is. A maximum of 1250 pages per month will not suffice any average office and this point will definitely lead to its unpopularity; unless they rectify it quickly.

How to Save Money On Printer Ink?

noreply@blogger.com (Tegap Jitu Enterprise) — Sun, 17 May 2009 15:36:00 +0000

Inkjet printers operate by propelling variably-sized droplets of liquid or molten material (ink) onto almost any sized page. They are the most common type of computer printer for the general consumer due to their low cost, high quality of output, capability of printing in different colors, and ease of use.

Like most modern technologies, the present-day inkjet has built on the progress made by many earlier versions. Among many contributors, Epson, Hewlett-Packard and Canon can claim a substantial share of the credit for the development of the modern inkjet. In the worldwide consumer market, four manufacturers account for the majority of inkjet printer sales: Canon, Hewlett-Packard, Epson, and Lexmark.

The emerging ink jet material deposition market also uses ink jet technologies, typically piezoelectric jets, to deposit materials directly on substrates.

Printer ink is very expensive and due to this the cost of running a printer is also very high. However, it is possible to save money on printer ink if you know what are the things to consider and where to buy.

The best way to save money on printer ink is to buy remanufactured cartridges or compatible cartridges for your printer rather than buying expensive OEM (Original Equipment Manufacturer) cartridges. Remanufactured cartridges are recycled OEM cartridges. Empty cartridges are professionally refilled by experts and then put up for sale. Compatible cartridges are third-party cartridges manufactured by companies who make cartridges for various printer types. Refilling your printer cartridge with a refill kit is also a good way of saving money. Refilling is the cheapest of all the options available.

Buying online can also save money on printer ink. Online sellers offer discounts and it will be easy to compare prices of various dealers and choose the best price. You will also be able to save on traveling and shipping expenses. Many sellers offer free shipping facilities on their products.

Having an extra cartridge at home will help save money on printer ink. If your printer suddenly runs out of ink, you don't have to go to the retail printer store and buy printer ink at a considerably higher price. If the number of printouts from your printer is too high then is it best to buy cartridges in bulk. Dealers will give huge discounts if you purchase in bulk. Bulk purchases are suitable for offices and large set-ups.

As printer inks are very expensive, the best way to save money on printer ink is to use it economically. Plan and print. Often people take printouts simply to realize later that it is not required. Take printouts of only those documents that are necessary.

Inkjet advantages

Compared to earlier consumer-oriented color printers, inkjets have a number of advantages. They are quieter in operation than impact dot matrix or daisywheel printers. They can print finer, smoother details through higher printhead resolution, and many consumer inkjets with photographic-quality printing are widely available.

In comparison to more expensive technologies like thermal wax, dye sublimations, and laser printers, inkjets have the advantage of practically no warm up time and lower cost per page (except when compared to laser printers).

For some inkjet printers, monochrome ink sets are available either from the printer manufacturer or third-party suppliers. These allow the inkjet printer to compete with the silver-based photographic papers traditionally used in black-and-white photography, and provide the same range of tones – neutral, "warm" or "cold". When switching between full-color and monochrome ink sets, it is necessary to flush out the old ink from the print head with a special

HP LaserJet 1320

noreply@blogger.com (Tegap Jitu Enterprise) — Sat, 16 May 2009 10:55:00 +0000

There's a reason Hewlett-Packard dominates the market for business-class laser printers. The company knows what business users want: solid performance, no-fuss design, good manageability, and solid tech support. The HP LaserJet 1320, a compact home and office monochrome printer, may not be the cheapest small-office laser available, but it delivers on the essentials and then some. It prints sharp, clean black letters and good graphics that suit professional manuscripts.

Quality of HP LaserJet Printer(Model HP LaserJet 1320)

Text became faint and spidery at 2.5- and 3-point font sizes, yet the letters didn't glob together. The text looked excellent at normal, readable sizes. At the default setting of 600x600dpi, our grayscale-graphics test document produced impressively smooth, evenly stepped shading from dark to light. The graphical and photo elements of our test document were short of perfect--a little grainy and lacking in detail. They noticed extraneous white dots on the border between a dark gray object and its black background, but when they bumped the quality setting up to ProRes 1200 (with a high 180 lines per inch), the finer halftone dots greatly improved the detail and clarity of photos and graphics.
SpeedThe HP LaserJet 1320 performed well in CNET Labs' tests, averaging 17.4 pages per minute (ppm) for text and 13ppm for graphics. While it didn't rip ahead of every laser machine, the 1320 ranked among the top small laser printers in its class, such as the Brother HL-5140, which printed text at 15.97ppm and graphics at 16.46ppm. They found no glitches with the reliable and quiet performance of the HP LaserJet 1320.

HP LaserJet Printer an Overview

noreply@blogger.com (Tegap Jitu Enterprise) — Sat, 16 May 2009 10:44:00 +0000

LaserJet is the brand name used by the American computer company Hewlett-Packard (HP) for their line of dry electrophotographic (DEP) laser printers.

HP LaserJets employ electro-photographic laser marking engines sourced from the Japanese company Canon. Most early printers used internal firmware, controllers, associated software, and drivers developed internally by HP and were considered their "value add" to the standard printer engines.
The first HP LaserJet and the first Apple Inc. LaserWriter used the same Canon print engine. The internal engine evolution differences were mostly superficial, with the main difference being in the onboard RIP controller, and the user-interface evolution (discussed below). This sharing of an identical Canon engine in two competing products continued with the HP LaserJet II/III and the Apple LaserWriter II, which also used the same internal Canon print engines.
Beginning with the LaserJet 4000, HP nearly completely outsourced its print-engine evolution work to Oak Technology, now Zoran Corporation, among many other suppliers, creating a much greater divergence in print-engine evolution between Apple and HP.

Upgrading memory of older models
Many older LaserJets and other HP printers, including LaserJet 4+, 4MV, 4MP, 4P, 5, 5M, 5MP, 5N, 5P, 5se, 5Si MOPIER, 5Si, 5Si NX, 6MP, 6P, 6Pse, 6Pxi, C3100A; DesignJet 330, 350C, 700, 750C, 750C Plus; DeskJet: 1600C, 1600CM, 1600CN; and PaintJet XL300 used proprietary 72-pin HP SIMMs for memory expansion. These are essentially industry-standard 72-bit SIMMs with non-standard Presence Detect (PD) connections. It is very often possible to adapt a standard 72-pin SIMM of appropriate capacity to support HP PD by soldering wires to pads, a simple task. HP printers of this type specify that RAM not faster than 70ns be used; this is probably due to a limitation of the PD encoding, and faster RAM can actually be used so long as the PD encoding indicates a speed of 70ns or slower. All printers will work with FPM (Fast Page Mode) memory; many, but not all, will work with EDO memory.

Bad News about Portable Laser Printer

noreply@blogger.com (Tegap Jitu Enterprise) — Wed, 13 May 2009 15:49:00 +0000

There are very few bad news to owning a laser printer in general but one of them is definitely the cost. The money that you could spend on a very high-end inkjet printer will only buy you a very low-end color laser printer with limited capacities. Color laser printers with multi-functions such as a copier and a fax all in one are even more expensive. However a middle of the line black and white laser printer is comparable to the price of a top of the line color inkjet printer.

Another disadvantage is the cost of the cartridges inside a laser printer. Sometimes the cartridges cost almost as much as the printer did which is why many people throw the entire printer out and buy a new one after the cartridge expires in year or two.

Speed -Laser printers are known for being fast. For basic, monochrome print jobs, some laser printers can produce upwards of 40 pages per minute. However the increased speed will be reflected in the price tag, so it's important to weight the cost against user needs.

The cartridges for laser printers are several times more expensive then the cost of the toner cartridges for inkjet printers. However they do last longer especially if you remember to set the printer in black and white printing mode when printing black and white and only using the color mode when it is really needed. Another way to make an expensive color laser toner cartridge last longer is to keep the printer in low quality mode unless you are printing out the final document.

If you live in a hot or humid climate a laser printer may not be the ideal solution for you. This is because running these machines can make a room very hot. The fuser inside them, which is the device that melts the plastic granules that constitute the powder that makes up the toner onto the paper, heats up to as high as 200 degrees Celsius.

Another limitation of a laser printer is that they only really print on certain kinds of paper. If you want to print out photographs then a laser printer is not for you as they are not yet capable of printing high-resolution images. Also you cannot put photographic paper through a laser printer. For the best quality images you need to buy a bubble jet ink printer that can transfer an image onto photographic paper. The color quality that you get with a bubble jet ink printer is just as good if not better than the color quality that you can obtain with a laser printer. A high-end color printer that produces quality color images can cost as much as $3,500 to $10,000 whereas you can get a good quality ink jet printer for about $200.

Another disadvantage of laser printers is that many of them are limited by the amount of memory that they are sold with. This can sometimes limit the number of fonts that you can use. To expand the memory of your color laser printer you usually have to buy a small RAM board. This is the only reliable way to install memory so that the color laser printer can utilize a number of fonts.

The more expensive a laser printer is the faster it is. The affordable models only print out about four pages a minute. Top end models print out about twelve pages a minute but they are not really affordable for the individual.

Laser printers, especially the color laser printers, can also be heavy and take up a lot of desk space or room in the office. At the time of writing there was also no such thing as a portable laser printer. The reason that a portable laser printer has yet to be invented is because a battery does not yet exist that is small enough to provide laser printer functions with enough power so that it can be taken on the road.

Durability - Laser printers have a lot of moving parts, and those parts can break down. However the parts can also be replaced or repaired. Laser printers generally have a fairly high duty-cycle rating and, when properly maintained and used within manufacturer's specifications, can last for many years.

Portable Laser printers provide better quality than ink-jet printers, but are more expensive. Keep in mind print quality, speed, reliability and price when deciding which printer to buy.

Step 1
Decide what types of documents you will be printing with Portable Laser Printer (text, graphics, odd paper sizes, etc.).
Double-sided printing (duplexing) used to be the exclusive domain of printers for corporate workplaces costing thousands of dollars. Now, you can get a printer for as little as $300 that will provide double-sided printing (e.g. the Lexmark E250DN). It’s well worth considering, because it will save you money in paper costs – not to mention saving a few trees too.

Step 2
Portable Laser Printer Features -Make a list of specific features you need, such as the ability to handle large files, the ability to print on various media (labels, envelopes) with-out jamming, a size to fit a particular desk space, two or more paper trays, and compatibility with specific software.

Step 3
Compare Portable Laser Printer of print quality of different printers. Compare the resolution, or dpi (dots per inch). Use a magnifying glass if print quality is critical. Printing quality is described in “dots per inch” (DPI). Laser printers generally offer 600 – 1200 dpi printing, and this is adequate to provide sharp printed text and reasonably smooth photos.

Step 4
Compare Portable Laser Printer speed specifications. Although you probably won't get the rated speed at home, the ratings are useful for comparing printers.

Step 5
Learn how much RAM the Portable laser printers have, and whether it's expandable.

Step 6
Paper for Portable Laser Printer- Realize that the printer's paper path needs to be no sharper than 90 degrees to consistently handle envelopes, labels, transparencies or card stock. If you plan to use special media often, avoid printers with 180- degree U-turn paper paths.

Step 7
Compare Portable Laser Printer prices of consumable items such as toner cartridges and replacement drums.
The most important thing you must do before buying a printer is to find out what the replacement toner cartridge costs. A $120 printer may have a $250 toner cartridge replacement cost, which will wear you thin before long.

Colour Portable laser printers are particularly bad in this respect, though some manufacturers price their consumables fairly. Be aware that depending on the design of the colour laser, there may be many different consumables you will have to periodically replace on top of the cartridges – the drum, the fuser unit, fusing oil, a waste toner bottle, and a developer unit. It’s a bit of a nightmare, and this alone may be enough to put people off buying a colour laser. After all, it’s a perfectly legitimate strategy to have a mono laser for your day-to-day printing needs and a colour inkjet for special colour documents.

Step 8
Compare warranties and service contracts for every Portable Laser Printer , find the attractive offer with reasonable price .

Most laser printers come with a 12 month warranty, and will often give good service for five years or more. Repairs are less of a problem these days than they once were, simply because laser printers are so cheap to buy that it’s not disastrous if it turns out they can’t be easily repaired – you can simply buy another one.

That said, beware laser printers from non-traditional electronics brands that are considerably cheaper than those from established brands. It may be impossible to get the printer fixed down the track when something goes wrong.

Buying a printer can be a complicated business, there are more shapes, sizes and types of printers available to the home and small business user than ever before. Printers have also become specialised for their intended purpose.

It is no longer a case of "a printer is a printer". Printers are now designed to be good in a particular area rather than a "Jack-of-all trades", which will do everything.

An often overlooked issue, is the very serious consideration of cost of ownership, which is all about of how much it will cost to keep your printer running (see below). So making that decision on which printer to go for can be a seriously arduous task, especially if you are keen to buy a printer that is not only affordable to buy but also cheap to run.

The information that you need to know and consider, but no one tells you! We have not expanded on which printer is the best at any given time because models constantly change and you can find that information in any current glossy PC magazine off the shelf. Instead, here you will find the good, bad and ugly bits from the different types of printers available so you can make an informed decision yourself.

How to Choose a Portable Laser Printer??

noreply@blogger.com (Tegap Jitu Enterprise) — Sun, 10 May 2009 16:56:00 +0000

What to Look For While Choosing a Portable Laser Printer

With the cost of printer ink these days, it's often tempting to just buy a whole new printer when your cartridges are empty. After all, you can buy a new printer for about the same amount as a set of black and color cartridges, right?

When it comes to choosing a portable printer, most major printer companies make them these days. Whether it is Canon, HP, Brother or any of the other well-known brands are offering an increasingly wider selection. There are portable printers that have the ability of just handling documents in black-and-white, or full color, or images that are of photographic quality, or even those that can produce high definition laser output.

Of course, your exact requirements will help you to decide on the right model. For example, what kind of printing will you need to do? Will you require color printouts or not? Will the quality of the printing be an important factor? And, what will be the volume of your printing?

Check Out the Inkjet Portable Printer: Amongst all the types of printers, the inkjet is considered the most versatile. They can be used for producing text, photographs, and graphics. The quality and accuracy is mainly dependent on the dpi, or dots per inch. The more the dots per inch, the better the quality, in terms of the sharpness of the graphics or text, and the colors and shades in photos.

However, the dpi can vary according to the kind of ink used, as well as the fonts, shading and colors. You will need to check out the quality yourself, which is best done by asking a reputable dealer to provide a demonstration. Inkjet printers use different kinds of paper according to whatever task needs to be done, and the type of paper used can influence the quality of the printing. For example, photographic paper will be required for printing photographs, and heavier bond will be used for printing business letters than required for reports or other documents.

If you do want to print photos, consider how much you'll spend on them. A photo printer can cost up to $1.00 per print by the time you consider ink and paper costs. You can get your pictures printed for much less than that at your local photo lab or on a website like Snapfish.com.

If you only want to print 4x6 photos, you might be better off buying two printers - one for your day-to-day use and a small photo printer that is designed just for printing 4x6 prints. They generally cost less to operate than their larger counterparts, and they are fairly portable if you want to be able to take it with you to make digital prints while on the go.

Who makes the best portable laser printer?

noreply@blogger.com (Tegap Jitu Enterprise) — Sat, 09 May 2009 06:37:00 +0000

Samsung and HP dominate the portable laser printer market; Samsung with its ML-1630 Monochrome Laser Printer and HP with P1005 or P1006 LaserJet printers. The Samsung model boasts a chic, low profile, easy for packing into cases and carrying with the business traveler, but at 14 pounds, you’d better have a case with wheels. The HP LaserJet models weigh slightly less than the Samsung offering, weighing in around 10 pounds, but they’re taller than the Samsung model and aren’t as convenient if you’re working with limited space. The Samsung portable laser printer provides a front-feed paper path, so you can stack objects on top of it, including your laptop.

Who needs a portable laser printer?

Business travelers are the primary audience for portable laser printers. They often find themselves needing to run prints on the road, and a portable laser printer could be exactly what the doctor ordered. While an increasing number of well-appointed hotels offer print centers for business travelers, it can be a bad idea to trust your print needs to a questionable hotel printer at eleven at night with an important presentation coming up the next day. What happens if the printer is out of commission, or if you have a technical problem communicating with the printer? Portable laser printers can eliminate all of these questions by providing a printer wherever you go.

Portable laser printer features vary.
The features that you’re likely to encounter on portable laser printers vary, but not as much as you might initially expect. As print technology improves, smaller printers don’t necessarily equal sacrifices in quality or functionality. In fact, portable laser printers are often quieter than their large office counterparts and are designed to require less space than workgroup laser printers.

You might sacrifice a little speed and you won’t find the workgroup or all-in-one functionality, but for the most part, portable laser printers boast similar features to the large stationary versions. Current portable laser printer technology doesn’t support scan, copy or fax functionality, as the scan lamp and technology drastically increases the size of the unit. However, you’ll find that portable laser printers are similar in almost all other aspects of technology.

What is a Portable Laser Printer?

noreply@blogger.com (Tegap Jitu Enterprise) — Sat, 09 May 2009 06:33:00 +0000

Portable print technology isn’t a new concept, but portable laser printers are still relatively new and far between on the marketplace. How is a portable laser printer different from its larger stationary cousin, and do you need one?

Portable laser printers: Portable is a relative term.
Many computer geeks argue that portable laser printers haven’t truly arrived, but that they’re not far off. While manufacturers advertise “portable laser printers,” the truth is that even these portable models are large and unwieldy, typically weighing in at 10-15 pounds. The mechanics involved in the technology of a laser printer make a truly portable laser printer unlikely. If a portable laser printer the size of a few laptops stacked together and slightly heavier isn’t a daunting prospect, then portable laser printers may provide what you seek.

The Truth About A Portable Laser Printer

noreply@blogger.com (Tegap Jitu Enterprise) — Sat, 09 May 2009 06:27:00 +0000

Having seen the title of this article, those of you in the know may already be thinking; what, did those clever computer scientists find a way to make a laser printer small enough to be considered portable? Unfortunately the answer is no, there is no such thing as a portablelaser printer , and we are going to consider the reasons why. First, let's take a basic look at how laser printers work.

Laser printers work on a page by page basis. The data that makes up the page is sent to the printer and the page does not start printing until the entire document is in the laser printer's memory. A laser scans across the surface of a drum that rotates, and flashes on and off to make a dot on the drum that has a different polarity to the rest of the drum. This dot attracts the toner to it-toner being a combination of powdered plastic and a colorant.

The drum is rolled across a piece of paper, transferring the toner to the paper. The combined paper and toner is then heated to approximately two hundred degrees Fahrenheit inside the laser printer, bonding the toner to the paper. This temperature alone requires a certain amount of space within the case, and space is at a premium with a portable printer.

Inkjet printers are far simpler and involve much smaller components. A liquid ink is passed out of the cartridge by varying methods that result in the ink being passed out, through a print head and onto the paper. The data is a continuous stream and printing can pause while waiting for more data, unlike with a laser printer.

Because of the way that the two machines work, they are sized very differently. Laser printers are large, and heavy machines that require large amounts of power to run the lasers and the produce the high heat needed to bond the toner to the paper-too much to be provided by a portable battery. Inkjets do not contain an imaging drum-instead producing the images through the print heads. The power required is much smaller, and hence is able to be supplied by a battery.

For this reason it is inkjet printers that are able to be made small enough to be portable. The lightest portable inkjet is just 2lb in weight, but the smallest laser printer currently is 10lb and 14 inches wide, by 9 deep. The size would be undesirable in a portable, the weight of a laser printer would be even less portable and there is another drawback.

Most laser printers are black and white only. Few are color and are hugely expensive. Portable printer users are most commonly business people, and being restricted to the monotone of a laser printer would not be good.

In the future perhaps technology will increase to the point that portable laser printers are possible, but for today, the only portable printer is an inkjet.
