Have You Filled Your Printer With Printer Cartridge


As a gun needs cartridges to shoot, printer needs printer cartridges to print. Printer is no more a computer accessory. It is no more an optional stuff. Today everyone prefers to go for a printer when they buy a computer. Printer has mostly reduced the hand written reports. Print outs are more preferred, whether in office or in school, as it is more convenient to read and even take less time to write than it is written by hand. But how these printer prints? Printer prints on paper with ink. The ink in these printers is in the form of the printer cartridges. Let us deal with this mystery and reveal it.

There are many types of printers. These are the dot matrix printer, inkjet printer, laser printer etc. Although all of the printers do the same job that is printing, their preferences are varied. Some would like to go for a dot matrix printer as they can print multiple pages through carbon copies while some people may like to go for laser printers as the dot matrix printer are too noisy. Dot matrix printer makes a lot of noise while printing on the paper. Dot matrix printers working are similar to the working of a type writer. Whatever may be the type of printer, printer cartridge is needed. Different types of printer uses different printer cartridges.

Printer cartridge is actually the ink that prints characters on the paper. It is the basic tool for the printer to work. Whether a printer is at home or in office, printer cartridge is essential to make mark on the papers. Printer cartridges include toner, ink refill, ink, and inkjet printer ink and top quality cartridges. Let me give you a technical overview on printer and how does it work? Printers are basically endowed with a flat ribbon that strikes and make an impact on the paper in the form of letters. The ink flows from the storage of ink in the printer to the ribbon. Malfunctioning of the ribbon make the printer disables to print characters on paper. Sometime some letters are missed when such happens.

Printer cartridges should always be selected cautiously. Go for the discounted printer cartridge but never compromise on its quality. Quality printer cartridge can offer you the best performance in printing. There are also color printers that print in colors. Colored printers have different printer cartridges. Printer is playing a vital role in the present economy. The success of your business in a way can depend on the printed paper that is depended on the printer cartridge. Your business document will reflect your efficiency and competence in the business. If your printer cartridge is not good at producing quality printing then it would create a bad impression on you client. It can even risk your deal to be finalized. So always check for the printer cartridge to avoid such redundant situation.

Keep excess printer cartridges in store. While printing some important documents, if your printer runs out of ink, what would you do? You may not have enough time to buy new printer cartridge. So always keep with you printer cartridge in surplus to avoid such situations.

Inkjet Printers Vs Laser Printers


For the most part, choosing a printer can be a daunting task and entails balancing price, speed, and print quality. In order to choose the right printer for you, you will have to ask yourself how much you print per month, what types of documents you will need to print, what quality print you require, whether or not you need color, and if you care more about the initial cost or cost over the printer's lifetime. The difference between inkjet printers and laser printers is day and night, but once you understand their differences and decide which type is most suitable for your needs, you are more than half-way to finding the right printer for you.

As a rule of thumb, laser printers produce crisp, speedy text documents and decent images, while inkjet printers produce top-quality, long-lasting photos and not-so-crisp text, all at an uncomfortably-slow pace.

Inkjet printers are best if printing high-quality photos are much more important that high-quality text and graphics and if speed is not an issue for you. Their major selling point is their superior color accuracy and print resolution for vivid photos, so this does add time to printing each page. They are also best if you have light printing needs and are more concerned with the cost upfront since replacing the ink cartridges can get pricey if you start to print a lot, but you can often find a good inkjet printer for under $100 or $200.

Laser printers are best if high-quality text documents are more important than high-resolution photos and that speed is essential. Laser printers major selling point is their ability to quickly print crisp documents at a very low cost per page. Color laser printers major selling point is their ability to print documents with a mix of text, graphics and photos at a fast speed, but they do run a bit more expensive because they can "do it all." Overall, laser printers and color laser printers cost much less to maintain and operate and have a lower cost over the printer's lifetime, but have a higher price-tag initially.

It's worth explaining in detail the huge difference in the cost of ownership of the two types of printers. An inkjet printer costs a lot less initially but its cost per page is much higher than a laser printer's cost per page. In fact, companies practically give away inkjet printers because the profit for most manufacturers is in the ink cartridges, or consumables as they call them. On the other hand, a laser printer costs a lot more initially, but over time its toner will cost much less per page. For example, let's say you print 5000 pages in two months. You would have to replace the inkjet's ink cartridges about 25 times compared with the two times you would have to replace the laser printer's toner cartridge. The cost of the inkjet ink cartridges would almost double the cost of the laser toner cartridges. If you print a couple hundred pages per month or a thousand pages per month, laser printers are more cost effective overall.

Conclusively, if your business' output volume is moderate to heavy, your best bet is to go with a laser printer due to the laser printer's total cost of ownership. If you print very infrequently, whether it's for personal use or for your small office, then an inkjet printer would be more cost effective.

At the end of the day, the types of documents you need to print may determine what printer, or printers, you select. If you're printing mainly photos and documents for personal use, such as directions in which you don't care about the quality, then you should get an inkjet printer. If you print a lot of text documents and are cost conscience, then a budget monochrome laser printer would be your best fit. Finally, if you print a moderate volume of text, graphics, and mixed documents, then a color laser printer would definitely best suit your needs and would be a good investment.

HP printers are great in both the inkjet printers and laser printers categories. Epson printers, Canon printers, and Kodak printers are very popular for inkjet and photo printers. Brother printers, Xerox printers, HP printers and Samsung printers are best in class for laser printers with Xerox probably the best in class for color laser printers for businesses. So figure out your printing needs and do your research and you will find the right printer for your needs at the right price.

In-Depth Printer Buying Guide


Working in Printer Consumable retailing, you would think that the majority of questions we receive would loosely revolve around "Which Ink should I use?", or "What cartridges will give me the best printing results?" If you find yourself agreeing with that statement, then come and keep me company in the I-was-wrong-corner. That's right. The number one topic of conversation we find is "What printer do you recommend?" Whether they're buying a new one themselves, or searching for a business contact, or just one of those people that really - REALLY - wants to be up to date with the top technology information, we get asked non-stop.

Whilst the temptation would be to fulfil our capitalist desires, recommend the printers which provide us with the highest margins and be done with it, amassing an untouchable army of customers utilising Printer-X to their own cost along the way (mwahaha), this is not how we do business. In fact, quite the opposite. We believe that our experience in the cartridges field, coupled with the fact we are not involved in the retailing of printers, leaves us in a prominent unbiased position for recommendations.

Whilst the following is not intended to denigrate or damage any manufacturer's reputation, it is our honest opinion which will hopefully lead you in your printer browsing task.

So, capitalist army-building aside, the actual question - What printer do we recommend? I wish I could put a single printer here, an all encompassing beast of a machine that excelled in anything you ever needed, and even did your Monday morning emails for you. But alas, my dreams are yet to reach fruition. The ideal printer for you is going to depend on a range of factors, which we will discuss and find out.

Firstly - what will you be using the printer for?

Now, stop your laughing at me for one moment, I know 99% of you read that and thought "Well, for Printing, idiot", and I accept your mocking tones and counter with:

o Purely for home use - letters, kids homework, neighbourhood watch pamphlets

o Quality printing, whether it is photos or image intense documents

o Small office use - mainly business documents on a reasonable scale

o Larger business use - high speed documents

Aha! Not as simple as you thought is it. Whilst you decide which of these areas you fit into, I will cheerily carry on with this article, thinking of my next way to stump you.

I'm a home printer:

Now that you've got that truth out in the open, and can move on with your life as a computer hardware (I'm a funny man), this category of printer means you need to focus on ease of use and cost. You don't want to be spending £'s each time your child prints a new spell-checked version of their homework, or you try out the new letterhead for your family Christmas letter X number of times. I shall start with the short and sweet part of this section:

AVOID - Old Hp and Lexmark printers, and Dell altogether

Now just imagine me shouting that at you, possibly accompanied by violent shaking, and you should get the sincerity of the warning. Just don't buy them. These manufacturers use an ink cartridge with a built in head, with all 3 different colours placed within this single cartridge. When one colour runs out, the cartridge is finished. Finish all your magenta printing, as who doesn't love red everywhere, and wave goodbye to any cyan and yellow you had stored away for a rainy day. This obviously means much higher printer costs than a system where the print head is built into the printer, with separate ink tanks for each colour so you just top up where needed. This system is utilised by Epson, Canon and Brother, making them immediately better value for you, and our recommended starting point for home printing.

Next you must consider what you want your printer to be able to do. Did you manage to stifle your "print things" laugh this time? I hope so. With multi-function printers offering a range of extras nowadays, such as scanning/copying/wireless networking, you really get a diverse choice. We do recommend spending the few extra pounds and getting one of the multi-function devices. In the long haul, the multi purposes it provides will tailor for any home needs you may encounter, and with all manufacturers providing them, their costs are competitive already.

Another advantage of these printers is a saving on following printing costs. With original cartridges approaching the actual cost of the printer, many can be tricked into an apparent bargain, then double their printing outlay as soon as the first cartridge runs dry. Home use printers opens up the avenue of compatible/refilled cartridges. With the only difference in quality being noticeable towards high end photo printing, they will be perfectly adequate for all home printer needs, and are significantly cheaper than manufacturer's original cartridges.

So what do we know? We are looking for a multi-function printer, made by Epson, Canon or Brother. Normally we would go into the hows and whys of using the printer, but the range of models for these manufacturers have really fine tuned the user experience, and we feel they all draw level on the usability test. So all 3 manufacturers carry on to the next stage, hooray. Multi function printers for these 3 providers is a great way to filter your browsing time, and anything after this is really more down to personal preference than a definitive answer.

For our overall recommendation, we would go for Canon each time.. They are reliable, cheap to run, and quality output! If you just want a printer that prints, go for the Canon ip4700. Want a multi-function? The Canon mp640.

Now that you've had my Home printing two-cents, I am going to break open the piggy bank in a splurge of valuable information for High Quality Photo printing.

Quality Image Printing:

Many people don't realise, but there are two types of imaging printers to choose from, outlined in the following to make you knowledgeable on all things image based.

The first to cast your mind's eye over is a process called dye sublimation. Ignoring the scientific jargon, it transfers dye onto your paper/card/fabric with heat one colour at a time. If you're really wondering, and want to show off, it's called sublimation as the dye goes from solid, to a gas state, to solid in the printing sequence, without ever being a liquid. Fancy. This printing method produces very high quality photo prints, typically equivalent or actually better than that produced by the traditional printing method employed in photo processing shops - the silver halide process.

In addition due to the sublimation method, there is very little mess, and the photos are instantly dry and ready to handle as soon as printing is finished. Also, due to the design of the printers, fewer moving parts than other styles of printers limit the potential for break down, maximising the longevity of the printers. However, this method is limited by sizes that you can print in, typically only found in the 6x4 print sizes, and can be expensive with the method utilising numerous panels for each colour. Couple this with a fact these panels cannot be reused, no matter how small an amount of ink was used of that colour, and your costs can quickly accumulate. Ultimately though, if you are looking for a pure photo printing experience, you can't go wrong with this printing method, and we recommend Canon as the manufacturer to side with.

If photo printing isn't the only quality image you're after, then dye sublimation may not be for you. With the transfer from a gas state to a solid, a small amount of diffusion (funny, and a scientist!) is unavoidable. Whilst this is not an issue with photos as it produces a very natural finish, when applied to sectors which require pinpoint accuracy, such as an architect's graphical outputs, this discrepancy is a weakness. Additionally, this technique of printing only works on special-coated paper, meaning an unavoidable inflexibility in what you print. This leads me on nicely to the alternative method of image printing, Inkjet printers.

In the past, this method was so inferior to dye sublimation that it would not have been considered, especially in the realms of photo printing. This was due to dye sublimation utilising "continuous-tone technology" where, in layman's terms, any dot in the photo can be any colour. This is contrary to inkjet printing which, as the name suggests, jets ink onto the page in droplets in scattered layers to create the image you are printing. Whilst this creates a smooth looking photo, focusing in on the photo would reveal visible droplets and not one smooth progression of the image. However, large advances in the technology of inkjet printers have seen the implementation of microscopic droplets, and a more diverse range of injected ink colours, providing a far superior picture than previously seen. Coupled with its accurate printing for the aforementioned architects drawing, its ability to use numerous materials to print onto, and the flexibility of image size, the new range of inkjet printers provide a much better overall package for your diverse printing needs.

If you trust us implicitly, and need no more information than the gold mine you have just treated your eyes to, then our best choice would be the Epson Stylus Photo R2880. Hard working, reliable, quality output, even my manager has one!

From the beauty of image printing, with the limitless potential of stunning scenery from photography, our exploration of purchasing a printer leads us naturally onto.... small office printing. What better way to dismiss the notion of grandiose panoramic views, than to the black and white (I'm sure they need colour at some times) monotony of the small office environment.

Small Office Printing:

Those of you whom have read the whole article will be glad to know that the requirement of these printers is very similar to that of the home printers, with low costs and good performance top of the agenda. You will be less pleased to note that these points will be repeated for those who skipped straight to this section. I will make it as painless as possible.

Firstly, the important points:

Do not purchase a Dell Inkjet printer, or the old range of HP and Lexmark printers. Whilst being good printers, they will not be cost effective for you. Utilising an ink cartridge with a built in head and three onboard colours, once one colour runs out you need a new cartridge. Infuriating in an environment specialising in black and white, with the occasional flash of colour for a company emblem or staff photo. This used to limit you to Canon, Epson and Brother printers, but the new ranges from HP and Lexmark mean that you have a very wide choice. All of these take advantage of separate slots for each colour, meaning that once one runs low, you just replace the individual colour.

So this is where your choice gets more difficult. Let us start with the simple decisions. Try and side towards the multi-function printers, which can cater for all the needs your office environment will place upon it. For only a slight increase in price, the additional practicality of the printer will be invaluable. The availability of compatibles for this range of printers is also worthwhile to note, with no degradation in quality for your office printing needs and a huge saving on overall printing costs.

Now, which manufacturers to look at. HP and Lexmark have a healthy dominance of this area of printing, with HP edging ahead with their latest range of printers. Interestingly, they differ completely in the type of ink they use, meaning your preference can easily help you choose which to side with.

Lexmark printers utilise dye based inks, the traditional ink found in the majority of inkjet printers, whilst HP printers utilise a newer pigment based ink. First used by Epson, this pigment based ink is made up of miniscule, encapsulated particles which sit on top of the paper, opposed to dye inks which are absorbed into the papers fibres. "Why should I care?" I hear you ask? Well, for your office environment, whilst these differences which typically only impact longevity of the prints and the colour quality, they also have implications for your costs. Dye based inks are known to soak into the page, lowering the efficiency of the cartridge per page, whilst pigment based ink has no such problem. Furthermore, pigment based inks typically have larger cartridges meaning you get even more prints for your money.

Whilst this is occasionally reflected in price, we tend to recommend siding with the pigment based inks, with a higher value for money being experienced.

This soaking effect leads onto another advantage of pigment ink. As soon as the page is filtered out onto the tray, it is touch dry. With no risk of smudging or ink dispersion that you can get with dye based inks, pigments guarantee the cleanliness and professional appearance of documents you print within your office. The longevity of prints is also a variable worth considering. With the filing systems employed at most offices you want your printed records to be durable and long lasting. Whilst advances in dye based ink have shown an increase in the lifetime of prints, pigment based inks still have the advantage.

Finally, dye based inks are not waterproof! Now I realise most offices do not work in downpours or go swimming for meetings, but the advantage of a pigment based ink being used to print a letter, which gets posted and delivery on a rainy day and stays legible, cannot be frowned at.

Ultimately we suggest the HP Officejet Pro 8500. A solid reliable printer from the new range of HPs, with fantastic per-page costs, backed up by quality pigment based inks.

In our final section we will be looking at the heavy duty office printing, for business's who scoff at any print speed lower than 15 pages per minute.

Business Use:

Colour Laser Printers. Thank you for reading. I hope this section was helpful for you.

In all seriousness though, with the fall of colour laser printer prices for under £200, your choice is made for you. Small footprints, networkable, and outstanding results from the chemical toners now in use, all lend itself towards a fantastic business printer.

The benefits of these printers just roll off the tongue:

o Faster print speeds

o Lower cost per page

o More robust

And this is just the starting point. An excellent quality range of compatibles presently available for a wide number of these printers means you can further save on your printing costs. In fact, the only reason we would say don't go for these printers is their apparent fussiness about the quality of paper being run through them. Ignoring the obvious "my printer is telling ME what I can print on?!?" issue, we found them to be temperamental when trying to print on the very cheapest 80gsm copies paper. However, upgrade to the 80gsm LaserJet paper which we use in all of our machines and the colour LaserJet's return to their serene performing best, causing us no problems at all. If you can afford it, stretch to the multi-function range of these printers, adding even more benefit to the small space these printers now take up.

This section may be the shortest, but it's because we believe your decision is such a formality. If we had to pick one and save you the effort, we would side with the Oki range, brilliant printers. With a superb output, nice gloss finish, and very cheap running costs with our excellent quality compatible range, your business will try and find reasons to print. That may be stretching the truth, but you got the idea. Specifically, the Oki c5650, but they are all quality products.

We hope this article has been useful for you, and that you all stop asking us what printer to buy.

HP Printer and Printers Shared on XP Workgroup - An Insight


Printer and Printers Accessories are required in almost every place. Nearly all offices, shops, and industries require printers for some reason or the other. A Printer is basically an output hardware device that prints texts or image tasks assigned to it from a computer. Present day operating systems offer many options for customizing a printer. You can also use advanced features like Printer Sharing that enable you to use a single printer over the network, i.e. from a number of computers. Many offices use the Sharing of Printers to make operation more economic.

This article would be helpful if you want to share a HP Computer Printer in windows XP professional workgroup network. Following are the steps you can use for Printer Sharing:

The whole process can be divided into two basic steps:

Step 1: Sharing the HP Computer Printer

First open the Control Panel and open the Printers and Faxes by double-clicking on the corresponding icon in Control Panel. Alternatively, you can click on Printers And Faxes on the Start Menu.In the Printers And Faxes windows that has appeared, right click on the printer you want to share and click on Sharing. But make sure that you have enabled the File and Printer Sharing for Microsoft Networks on network card's properties.In the window that appears, click the Sharing tab and select the Radio-Button named 'Share This Printer'. Assign a share name to the computer, say HP Printer and Printers; this is the name with which your printer will be known on the network. Click OK.

Step 2: Connecting the Shared HP Printer

Now start the computer where you want to use the shared printer, HP Printer and Printers. Open the Printers and Faxes window in the same way as you did in Step-1.Now click on file on the menu bar and select Add Printer. The Add Printer Wizard will open.Clicking Next on this Add Printer Wizard will take you to the next page, where you have to select whether you wish to install a Local Or Network Printer. Select 'A Network Printer, Or A Printer Attached To Another Computer' and click Next.On the Specify A Printer page, select the option Browse For A Printer and then click Next.On the Browse For Printer page that appears, reach your shared printer named HP Printer and Printers and select it. For this you may have to expand the groups by clicking the Plus sign '+' next to them.Click Next after selecting the shared printer. A dialog box will appear asking whether you are sure to install the driver for the printer. Click Yes and then Finish.

Now-a-days, printers come in many varieties and models.

Getting Started With Your New Printer


If you have recently bought yourself a new printer, follow the directions in the manual for setting up cables. Put the installation CD into the CD drive and follow the set up instructions.

If you are using Windows 95/98, select Start Menu, then select Printers. Now select Add Printer, select Local Printer. Choose your printer (If your printer is not listed, choose the one closest to yours and select OK).

For the Mac, select go to server, (or chooser) and then select printer. Then choose your printer. (If your printer is not listed, then select the closest one.) Then select install.

If you are using Windows XP, then the PC will prompt you for the drivers and install the relevant one from the CD itself (if the appropriate driver is not in the database already).

If you have any problems printing, first check your cable connections. If you get repeated error messages, then reboot your computer and redo the steps above.

If you would like to upgrade the driver of your currently installed printed, then follow the steps given in the next sub-topic.

Installing Printer Drivers

A printer driver is a piece of software that allows the computer to communicate with the printer. Without this software, the printer would be hopelessly lost since it does not speak the same language! Printer manufacturers often update the drivers and these they can be easily downloaded form the company’s website for free. It is a good idea to keep a check on your printer driver version and upgrade if it is too far out of date.

Here is how you can check your print driver version number:

Windows XP

1. Click the Windows Start button, choose Control Panel, and then choose ‘Printers and Faxes.’

2. Right-click your default printer and choose Properties. (Your default printer will have a checkmark within a black circle above the printer icon.)

3. Click the General tab, click the ‘Print Test Page’ button, and then click OK to print the test page.

Windows 95/98

1. Click the Windows Start button, choose Settings, and then Printers.

2. Right-click your default printer and choose Properties. (Your default printer will have a checkmark within a black circle above the printer icon.)

3. Click the General tab, click the ‘Print Test Page’ button, and then click OK to print the test page.

Look on the test page for Driver Version.

All major printer manufactures have web sites that allow you to freely download their printer drivers. To do so, you will need your printer’s manufacturer and model number. When you go to the web site, look for words such as ‘Downloads’, ‘Drivers’, ‘Software’, or ‘Support’ and shortlist your model.

Given below are the website URLs for the popular brands:

Hewlett Packard — http://welcome.hp.com/country/uk/en/support.html?pageDisplay=drivers

Canon — http://software.canon-europe.com/

Epson — [http://emeasupport.epson-europe.com/downloads.aspx?LNG=en-EU]

Lexmark — [http://support.lexmark.com/cgi-perl/selections.cgi?ccs=227:5:0:0:0:0&target=http://downloads.lexmark.com/cgi-perl/downloads.cgi&&req=:::::]

Troubleshooting Printer Problems

In this section, you’ll find some of the more common problems that cause 45 percent of the help centre phone calls.

If nothing has occurred since the last time you used your printer, chances are the problem is quite straightforward. As obvious as it sounds, check to ensure that the printer is turned on. It is quite possible that somebody might have turned it off while you were away from your desk or computer. Make sure the printed is connected properly and there is power to the printer. All printers have some kind of LED that lets you know if it is powered up.

If the printer is turned on but has some flashing lights, then check with your owner’s manual to see what the lights mean. Most of these indicators will be related either to paper, ink, or toner.

Make sure there is enough paper in the printer. Refill the paper tray if it’s empty. Make sure you ‘fan’ the paper stack before putting it in the printer. When the paper stack is cut and packed at the factory, it sometimes causes the pages to stick together. Fanning the paper simply involves flipping through the paper stack with your thumb. This ruffling separates the paper, thereby reducing paper jams.

If the paper is stacked well, then check for a mis-feed or paper jam. Remove the paper stack and check the feed area for jammed paper. You may have to open several panels to make a thorough examination. Even a small piece of paper stuck inside the printer can cause problems. You might have to use tweezers to remove small pieces. Be careful of any contact of the tweezers with printer parts to avoid any damage.

If everything listed above is in place, then check the wire that connects the printer to the computer. You may be using a parallel or a USB connection. Make sure the cable is connected properly. Turn the equipment off and remove and re-insert the connection on both the printer and the computer to ensure a solid connection. If you are at work and your printer is connected to what appears to be a telephone wire, then you should call your resident network expert.

If the printer is functioning but only seems to print illegible garbage, then that is a good indication of a printer driver problem. Try re-booting the computer and turning the printer off and on before making any changes to the driver. If after re-booting you still have the problem, it's probably time to replace the printer driver. You can download the driver from the website URLs listed earlier in this articles. Follow the instructions given by the manufacturer to install your driver.

Scanner can also sometimes interfere with printers. Try re-installing the software for both but install the printer driver first, and the scanner driver afterwards.

If nothing listed above results in a solution, then perhaps it might be time to call the printer manufacturer. Make sure that you are near the printer when you call and have all your warranty information available at hand.

Difference Between Impact Printers And Nonimpact Printers


What are printers? A printer is an output device that prints characters, symbols, and perhaps graphics on paper. The printed output is generally referred to as hardcopy because it is in relatively permanent form. Softcopy refers to temporary images such as those displayed on a monitor. Printers are categorized according to whether or not the image produced is formed by physical contact of the print mechanism with the paper. Impact printers have contact; nonimpact printers do not.

Impact printers

An impact printer has mechanisms resembling those of a typewriter. It forms characters or images by striking a mechanism such as a print hammer or wheel against an inked ribbon, leaving an image on paper. Impact printers are dying out; however, you may still come in contact with a dot-matrix printer. A dot-matrix printer contains a print head of small pins that strike an inked ribbon, forming characters or images. Print heads are available with 9, 18, or 24 pins; the 24-pin head offers the best print quality. Dot-matrix printers permit a choice between output of draft quality; a coarser-looking 72 dots per inch vertically, which may be acceptable for drafts of papers and reports, and near-letter-quality, a crisper-looking 144 dots per inch vertically, which is more suitable for a finished product to be shown to other people.

Dot-matrix printers print about 40-300 characters per second (cps) and can print some graphics, although the reproduction quality is poor. Color ribbons are available for limited use of color. Dot-matrix printers are noisy, inexpensive, and they can print through multipart forms, creating several copies of a page at the same time, which ninimpact printers cannot do.

Another type of impact printer is not used with microcomputers. Large computer installations use high-speed line printers, which print a whole line of characters at once rather a single character at a time. Some, called chain printers, contain characters on a rotating chain; others, called band printers, contain characters on a rotation band. Speeds of up to 3000 lines a minute may be possible with these machines.

Nonimpact Printers

Nonimpact printers, used almost everywhere now, are faster and quieter than impact printers because they have fewer moving parts. Nonimpact printers form characters and images without direct physical contact between the printing mechanism and the paper.

Two types of nonimpact printers often used with microcomputers are laser printers and ink-jet printers.

Laser Printer: Like a dot-matrix printer, a laser printer creates images with dots. However, as in a photocopying machine, these images are created on a drum, treated with a magnetically charged ink-like toner (powder), and then transferred from drum to paper.

- There are good reasons why laser printers are so popular. They produce sharp, crisp images of both text and graphics, providing resolutions from 300 dpi up to 1200 dpi, which is near-typeset quality (NTQ). They are quiet and fast. They can print 4-32 text-only pages per minute for individual microcomputers, and more than 120 pages per minute for mainframes. (Pages with more graphics print more slowly.) They can print in many fonts (type styles and sizes). The more expensive models can print in different colors.

- Laser printers have built-in RAM chips to store documents output from the computer. If you are working in desktop publishing and printing complicated documents with color and many graphics, you will need a printer with a lot of RAM. Laser printers also have their own ROM chips to store fonts and their own small dedicated processor. To be able to manage graphics and complex page design, a laser printer works with a page description language, a type of software that has become a standard for printing graphics on laser printers. A PDL (page description language) is software that describes the shape and position of letters and graphics to the printer. PostScript, from Adobe Systems, is one common type of page description language; HPGL, Hewlett-Packard Graphic Language, is another.

Ink-jet printer: Like laser and dot-matrix printers, ink-jet printers also form images with little dots. Ink-jet printers spray small, electrically charged droplets of ink from four nozzles through holes in a matrix at high speed onto paper.

- Ink-jet printers can print in color and are quieter and much less expensive than a color laser printer. However, they are slower and print in a somewhat lower resolution (300-720 dpi) than laser printers. Some new, expensive ink-jet printers print up 1200 or 1400 dpi. High resolution output requires the use of special coated paper, which costs more regular paper. And, if you are printing color graphics at a high resolution on an ink-jet printer, it may take 10 minutes or more for a single page finish printing.

- A variation on ink-jet technology is the bubble-jet printer, which use miniature heating elements to force specially formulated inks through print heads with 128 tiny nozzles. The multiple nozzles print fine images at high speeds. This technology is commonly used in portable printers.

Things to take into account when buying a printer, is the printer easy to set up? Easy to operate? Do I need color? or black will do? Does the manufacturer offer a good warranty and good telephone technical support? Otherwise it's wise to own your own personal printer and get to know the answer to these questions.

Disturbing Facts About Expensive Printer Ink Examined


The truth of this article will knock your socks off. Everyone knows that printer ink is expensive, but few recognize just how expensive it actually is. Printer ink is one of the most expensive things that you'll run into when operating an office and it requires frequent replacement. It is used at home, school, office and more, and is an essential resource for busy people. It adds up to a real expense, and the demand is high. Let's face it, printer ink is big business today. As a matter of fact, it is a $32 billion market worldwide

Printer Ink is affiliated with Inkjet Printer Cartridges. However, note that there is a difference between printer ink and printer toner. Printer ink is a liquid that is applied to paper by pressure in the form of small droplets. Each time a nozzle fires, a new supply of printer ink is automatically drawn into its chamber, making it ready to again be is sprayed onto the page in a complex pattern of tiny dots. But what is so unique about this ink? .Keep in mind that all printer ink is not universal and it is manufactured very differently from normal pen ink. The manufacture of printer ink is a closely guarded secret, and the process and formula is patented. But, have you ever wondered what goes into printer ink? Printer ink is 99% distilled and possibly de-ionized water with pigment added for color. Interestingly, black printer ink is an equal mixture of three ink colors--"cyan, yellow and magenta." Printer ink is transparent to infra-red light, and most of it acid free. Knowing the following will alert you to the need for certain cautions when using of printer ink. Be aware that it is not waterproof and also be aware that it can be smudged before it dries. In addition, low quality ink tends to fade more than the higher quality ink. This is especially important to know when printing on photo paper. Since using top quality printer ink is essential for obtaining the brightest and most precise, and long lasting images, it is wise to use only top quality ink.

Would you believe printer ink is the most expensive liquid on Earth. Printer ink is more expensive than oil or vintage champagne. Ounce for ounce, printer ink is more costly than gold. It is without a doubt the most ridiculously high priced technological necessity on the planet. The printer ink market is cleverly built on the Gillette business plan. That is to sell the razors cheap and charge big for the cartridges. Thus we find printers reasonably priced, but pay through the nose for the ink. Japan retains a huge monopoly on printer ink and maintains the high prices quite successfully. In addition, printer ink is notoriously over-packaged, and this adds to the already lucrative price. It is very clear that the printer manufacturers have a vested interest in printer ink and they want to protect and monopolize the sales. Therefore, they are not hesitant to warn that only their proprietary brand of ink should be used in their printers. While we have to accept that printer ink is not cheap, let's examine the matter a little further.

Now that we know that printer ink is tremendously over priced, what can we do about it? We tell ourselves that we must print this and that, but do we have spend a fortune to do it? Well, here are a few suggestions that may help. For one, realize that running out of ink can add to your expense. This is true because running out of ink may involve some waste in the recharging process and may also be detrimental to your printer. Therefore, watch for streaking that may indicate that you are running out of ink. Then stay ahead of being overwhelmed by your computer screen flashing a message that tells you that your printer ink is low. Be ready to replace your ink immediately when it is needed. Ideally, one should be well stocked with printer ink and paper before you print your document.

Saving on printer ink is more than buying the ink at the lowest price. Before you buy printer ink, it is important to know which type of printer ink is needed for your printer. High quality ink is crucially important for good image results and to insure proper printer function. Regardless of your printing need, it is recommended that you use only high quality ink that meets or exceeds the original equipment manufacturer (OEM) standards. Only then should you consider the cost. Remember that OEM proprietary ink always demands a premium price regardless of where you shop. This leads to finding where you can make the best buy. Keep in mind that printer ink is a huge money maker for stationery stores, computer stores, and discount stores. It fact, it is one of the most profitable items they sell. But, dispel the notion of rushing to the nearest discount store. The cost will still be outrageous. So what is the solution? To begin, consider buying generic brands instead of OEM brands. However, make sure you stick to high quality ink that is up to the required standards. The internet offers the best place to buy quality printer ink and save money. A moderate purchase often receives free shipping.
