Laser printers designed to produce a standard and/or high-definition, permanent, color text or graphic copy (i.e., hard copy) on full-size (e.g., letter, legal) and/or nonstandard, large-format paper or other appropriate media by adhering colored toner (fine particles of plastic powder mixed with coloring agents, usually cyan, yellow, and magenta) to a light-sensitive print drum using a laser source. The toner is transferred to the printing medium (usually common paper) using static electricity, and then the toner is fused to the paper using heat and pressure. These printers typically include a revolving photosensitive drum, a laser source (e.g., a laser diode), a toner cartridge, rollers that apply heat and pressure to the paper, a rubber blade to remove excess toner, controls, and paper trays. Color laser printers are intended mainly for use as computer peripherals and/or by computer network users, providing high-definition color hard copies at a relatively high printing speed.
