Printer:
A printer is an output device that produces text and graphical on a physical medium such as paper.

Laser printers are faster than ink jet printers. Their speed is rated in paper per minute (ppm).


The primary steps in the laser printing process are listed below:
1.      Clean: Any remaining toner is cleaned from the drum.
2.      Charge: A high electrostatic charge is placed on the surface of the drum.
3.      Write: The laser is rotating on a fixed surface and some under program control the full system.
4.      Develop: Toner, vary fine particles of plastic and carbon, to attract to the charged areas of the drum.
5.      Transfer: A strong electrical charge is placed on the paper, causing the toner to transfer from the surface of the drum to the surface of the paper.

6.      Fuse: Heat is used to fix the toner to the paper.
