A type of high-speed printer used with computers. The characters to be printed are formed by a low-power laser, which alters the electrical charge on appropriate areas of the surface of a photoconductive rotating drum, as in xerography. The drum is selectively coated with a toner powder, which is attracted by the charge produced by the laser but repelled by that on the rest of the drum. The powder is transferred to paper and fused into place by heated rollers. Laser printers are very fast and silent, producing high-quality lettering and graphics. They are often used with desktop publishing equipment to produce reports, catalogues, and newsletters.
