A common type of high-quality computer printer.
Laser printers work on the same principles of xerography as regular photocopiers. A static charge is formed on a rotating drum using a computer-controlled laser beam (in the case of a laser printer). Dry powdered toner adheres to the statically-charged sections of the drum and is then transferred onto the paper. A heat roller then permanently melts the plastic toner onto the surface of the page.
Laser printers are commonly used today in high-quality fast office laser printers; usually black and white only. Colour laser printers are expensive and not as common.
cf. dye sublimation, inkjet, toner.
