Laser printer

A non impact computer printer. It uses a laser to dissipate an electrostatic charge in specific areas of a light-sensitive drum, which then picks up toner by electrostatic attraction. The toner is then transferred to a sheet of paper to form an image which is fused into place by heat and pressure. Related but now obsolete analogue photocopiers use much the same process, but with reflected and focussed light bounced off the original that is being copied.
