Definition
Noun: A type of computer printer that uses a laser beam to produce an electrostatic image on a photosensitive drum. Toner (a fine powder) is then attracted to this electrostatic image, transferred, and fused onto paper to create the final printout. It is known for high-speed, high-quality text and graphics output.
