Colour Laser
A laser printer uses the same printing technology used an office copier, except a beam of laser light under computer control is moved to draw an image on a charged photosensitive drum or belt. Where the light hits, the charge is destroyed. Small carbon particles called toner are applied to the drum or belt, and they stick to the areas that still are charged. This toner image is then transferred to paper and fused to the paper by heat or pressure.
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 colour) at fantastic speeds.
