Computer printer

From Simple English Wikipedia, the free encyclopedia

A printer is a piece of hardware for a computer. It is an instrument that must be connected to a computer which allows the users to print items on paper, such as letters and pictures. It can also work with Digital Cameras to print directly without the use of a Computer.

[edit] Types of printers

Today, the following types of printers are in mainstream use:

  • Inkjet printers, also sometimes called bubble jet printers use colored ink they put on a paper.
  • Plotters are large format inkjet printers, or printers that use special pens.
  • Laser printers transfer tiny particles of toner onto the paper.
  • Dot-matrix printers are now almost extinct. They used a ribon and made a lot of noise. There were models with 9 pins and models with 24 pins.

[edit] Cost of printers

Usually, laser printers are more expensive than inkjet printers. Inkjet printers on the other hand have a higher cost of consumableas, the ink tanks are more expensive than the toner. Laser printers that can print color are still quite expensive.
