A laser printer is a common type of computer printer that produces high quality text and graphics on plain paper. Like photocopiers, laser printers employ a xerographic printing process but differ from analogue photocopiers in that the image is produced by the direct scanning of a laser beam across the printer's photoreceptor.

Overview

Laser printers have significant advantages over other types of printers. Unlike impact printers, laser printers can mix text and graphics, including varied fonts and character sizes, and halftone images. Laser printers use toner, a black or colored powder, rather than liquid inks. Get all your HP printer supplies including printer ink, cartridges, toner, photo paper and more. Unlike thermal printers, whose images can be smeared if the paper comes in contact with a source of heat, laser printers do not require special paper. Advantages of laser printers over inkjet printers include higher resolution, no smearing, lower cost per page, and faster print speed, since the entire page is imaged at one time, while an inkjet typically prints a series of narrow strips. However, laser printers always produce raster images, and except in the highest-quality versions, are less able to reproduce continuous tone images such as photographs.

The slowest laser printers produce about 4 pages per minute (ppm), and are relatively inexpensive.
