laser printer

Computer

An electrophotographic printer in which a laser is used as the light source; the laser beam is modulated to produce the image. The term is also often used to refer to page printers of this type that use LEDs or LCDs as the active element. This type of printer is now very widely used as an office printer, frequently shared among a number of users. Most laser printers use single sheets of paper or transparent media and provide media-handling facilities; some can handle 50 pages per minute. Laser printers produce a very high standard of print. The higher-end range of laser printers now offers resolutions of 1200 dots per inch. Colour laser printers are also available.

Electronics and Electrical Engineering

A device that prints text or graphical images onto paper or plastic film. It consists of a laser beam directed at a rotating drum, so that the electrical charge on the drum is changed where it is struck by the beam. The drum, as it rotates, passes through a tank of toner (particles of ink in powder form). Where the drum is charged it picks up ink. The drum then contacts the paper or film to be printed and transfers the ink to the paper or film through heat and pressure.
