Definition And Types Of Printers

Printer

After a document is created on the computer, it can be sent to a printer for a hard copy (printout). Some printers offers special features such as colored and large page formats. Some of the most commonly used printers are:
  1. Laser Printer
  2. Ink Jet Printer
  3. Dot Matrix Printer
  4. Line Printer
Laser Printer: A laser printer produces high quality print that one normally finds in publishing. It is extremely fast and quite. Moreover, the operation of a laser printer is easy with automatic paper loading and no smudging or messing up of ink ribbons. The fastest laser printer can print up to 200 pages per minutes in monochrome (Black and White) and up to 100 pages per minutes to color.

Ink-Jet Printer: An ink-jet printer creates an image directly on paper by spraying ink through as many as 64 tiny nozzles. Although the image it produces is not generally quite as sharp as the output of a laser printer, the quality of ink-jet images is still high.

In general, ink-jet printer offers an excellent middle ground between dot matrix and laser printer. Like laser printer, an ink-jet printer is quite and convenient, but not particularly fast.

Typically, an ink-jet printer is more expensive than a dot-matrix printer, but costs only half an much as a laser printer.
