Printers: Categories and Functions

A printer is a computer peripheral that puts texts and computer-generated image on paper. Printers can produce books, magazines, newspapers and other reading material that are stored by the computer.

Categories of Printers

I. Impact Printer
Impact printer acts as a raid for the paper. These printers are demonstrated by pin dot-matrix printers with daisy-wheel printers. It strikes the paper that is being printed.

II. Non-impact Printer

Non-impact printer includes every other type of print mechanism. This includes laser, ink-jet and printers that are thermal.
III. Other possible categories of printers are the following:

• Technology of Printing

The principal and topmost of these are the pin dot-matrix, ink-jet, laser, thermal, and (although it in now outdated) daisy-wheel, also known as the thimble printers. All of these have a microcomputer. In addition, pin dot-matrix printers can further be categorized by the number of pins in the print head that is: 9, 18, 24, and so on.

• Character Formation

Character formation is fully formed characters made of unceasing lines. An example is those that are produced by a daisy-wheel printer. Thus, dot-matrix characters that comprises with patterns of dots. Laser printers, technically known as the dot-matrix, are generally deliberated to produce characters that are fully formed. This is because their output is very sharp and the dots are greatly small spaced.

• Method of Transmission

In this category the printer refers to the means by which the output will be sent to the printer. It is not by means of mechanical distinctions. There are a lot of printers that are available in either serial or even parallel versions. Despite of this, some still offer printer that has both choices. In this way, printer can produce greater flexibility in installation options.

• Printing Method

Character printer includes a standard dot-matrix, ink-jet, thermal, and daisy-wheel printer that print character per character, line per line, and page per page. On the other hand, line printers are the ones that include the band, chain, and drum printers. These are commonly associated with a very large computer installations options or networks that are going to be used. Page printers, popularly known as the laser printers include the printers with electro-photographic images and texts.

• Printing Capabilities

The most commonly known as the text-only printers are the daisy-wheel and the thimble printers. Some dot-matrix and laser printers can duplicate characters only for which they have matching patterns. Example of this is the ones with embossed type or internal character maps. On the other hand, printers that can print texts and graphics such as dot-matrix, ink-jet, laser, and many more can produce all types and way of images and pictures including the "drawing" of each that is served as a pattern of dots.

Printers Brisbane can reproduce, copy, duplicate, and imitate everything that one can wish to print in a possible way that it can be read by the printer. This means that a hard drive such as printer drive, CPU and monitor is available. Without printers reading daily newspapers, books, magazines and other material that is being produced is impossible.
