Different Types of Computer Printers
Early computer printers operated much like an old-fashioned typewriter. A letter shaped drum made up the ink panel, which was then covered with a piece of electrically charged paper. Later models used a series of tiny pins to form words from individual dots, thus being referred to as "dotset" printers. In the case of dot matrix printers, the letters of the alphabet are printed in a grid on the screen, much like a telephone keypad.

Dot Matrix Display (DML) is a subset of full dot matrix display. It was the first system for color printers, and is available today on most laser and inkjet printers. DML produced vivid, accurate color images. Though not quite comparable to modern laser and inkjet printers, DML did have several advantages over its predecessors, including lower cost, shorter maintenance, and better compatibility with operating systems.

The advantages of DML were twofold. With DML printers, you could reproduce highly detailed, art-style artwork in mere minutes. Before DML, home graphic artists and greeting card designers typically waited hours to complete a meaningful work of art, sometimes far longer than the time it would take to print a standard-sized document. Second, by using this form of color printing, you could utilize the same ink for every page of your document, greatly reducing waste and eliminating costly cartridge refills. DML printers also simplified the process of sending files to friends and family abroad.

Laser and inkjet printers are both excellent choices for printing text, though DML has definite advantages in certain situations. DML is obviously more expensive than dot matrix printers, even when considering cost-per-page (CPM) costs. However, the cost of the technology, relative to other technologies, is growing. For example, dot matrix printers are becoming cheaper all the time.

By the time you print one sheet of text using a typewriter, the cost is often well worth the additional cost of ink. At the same time, computer printers can take many hundreds or even thousands of sheets of paper before requiring re-wetting. In addition, most typewriter users recognize the process of transferring a printed page from a ribbon feeder (where paper fed from the ribbon onto the computer monitor) to a computer printer.


A dot matrix printer is often the best choice for someone who does a great deal of printing for a company. These types of printer have a high dot resolution (dpi), which enables very accurate color reproduction. The majority of these machines are available with a laser pointer as an add-on option. Although some use a thermal printer, the bulk of the price comes from the speed of the printer. These printers use oil-based inks and print at a very high print speed.

Some of the smaller home office printers are available for a fraction of the price of larger models. For example, a standalone printer can usually be purchased for under $100, although some of these are dedicated print machines. A desktop PC printer uses a variety of technologies including inkjet, thermal, laser, and bipolar. All of these are typically available for under $200.

Thermal and laser printers use inks on paper heated by a laser. Computer paper is coated with inkjet and thermal inks. This coating ensures that the print heads can be blackened to prevent fading, and the ink is much more durable. The small print heads are not as robust as dot matrix, but they are still very dependable.

Dot-matrix printers are typically used for higher volume printing of photos and illustrations. The cost of this type of printer is determined by the amount of printing that it can handle. If you need to print a lot of text, documents, or images, then you will likely find the best value in a plotters printer. dot-matrix printers are also typically only good for business applications because they are limited by the amount of ink that they can handle and their high start up costs.

The inkjet printer works by spraying a colored inkjet onto paper. There are many inkjet printers, depending on your requirements. These printers generally operate by using either a ribbon system or a daisy wheel technique. In the daisy method, there are two ink bottles, one positioned under the feeder arm and the other beneath the paper holder. how do i get my canon printer to scan to my computer? You must place the bottles so they are perpendicular to the paper surface.

Inkjet printers have higher resolution than other methods and they are typically more expensive, but they are perfect for printing high resolution graphics. If you are looking for an affordable printer suitable for both home users and professionals, the inkjet printers are the best options. They are available in both vertical and horizontal models, with each having its own benefits. It is important that you understand exactly how the ink will be applied to the paper before choosing which model to purchase. Although inkjet printers are generally quite affordable, you should also consider the cost of replacement cartridges as they can cost more over time.
