| laser printer
While considerably more complex and
expensive than most other common printer types, laser printers are capable
of producing extremely high-quality text and graphics (including color) at
fantastic speeds. At their most basic, laser printers apply an
electrostatic charge to a drum inside the printer cartridge. A laser or a
light-emitting diode then discharges portions of the drum to form the
characters or graphics. Charged toner attaches itself to these discharged
sections. A charged piece of paper is passed over the drum, transferring
the toner. The toner is heated and fused to the sheet. |
