HP LaserJet 1320

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


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



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.

Buy a Portable Laser Printer - User Guide



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.

Portable Laser Printers - A Practical Buyers Guide



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.

What is it?? You can read at next post....

How to Choose a Portable Laser Printer??



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.
