laser printer

noun
Computers. a high-speed printer that uses a laser to form dot-matrix patterns and an electrostatic process to fuse metallic particles to paper a page at a time: capable of producing a variety of character fonts, graphics, and other symbols.

laser printer definition


A type of printer that provides high-resolution images. A laser produces an image on a rotating drum, which is then rolled through a type of ink that transfers to the places illuminated by the laser.

laser printer definition

printer
A non-impact high-resolution printer which uses a rotating disk to reflect laser beams to form an electrostatic image on a selenium imaging drum. The developer drum transfers toner from the toner bin to the charged areas of the imaging drum, which then transfers it onto the paper into which it is fused by heat. Toner is dry ink powder, generally a plastic heat-sensitive polymer.
Print resolution currently (2001) ranges between 300 and 2400 dots per inch (DPI). Laser printers using chemical photoreproduction techniques can produce resolutions of up to 2400 DPI.
Print speed is limited by whichever is slower - the printer hardware (the "engine speed"), or the software rendering process that converts the data to be printed into a bit map.
The print speed may exceed 21,000 lines per minute, though printing speed is more often given in pages per minute. If a laser printer is rated at 12 pages per minute (PPM), this figure would be true only if the printer is printing the same data on each of the twelve pages, so that the bit map is identical. This speed however, is rarely reached if each page contains different codes, text, and graphics.
In 2001, Xerox's Phaser 1235 and 2135 (with Okidata engines) could print up to 21 colour ppm at 1200x1200 DPI using a single-pass process.
Colour laser printers can reach 2400 DPI easily (e.g. an HP LaserJet 8550). Some printers with large amounts of RAM can print at engine speed with different text pages and some of the larger lasers intended for graphics design work can print graphics at full engine speed.
Although there are dozens of retail brands of laser printers, only a few original equipment manufacturers make print engines, e.g. Canon, Ricoh, Toshiba, and Xerox.
