Laser printing is an electrostatic digital printing process. It very rapidly produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back & forth over an electron-charged, cylindrical drum, to define a differentially-charged image.^[1] The drum then selectively collects electrically-charged, powdered ink (i.e., toner), and transfers the image to the loaded paper, which is then heated in order to permanently fuse the text/imagery. As with digital photocopiers and multifunction/all-in-one inkjet printers, laser printers employ a xerographic printing process; but, laser printing differs from analog photocopiers in that the image is produced by the direct scanning of the medium across the printer's photoreceptor. This enables laser printing to copy images more quickly than most photocopiers.
