Not to mention the much larger range of techniques used, which have nothing to do with those we know from home printers.Printed roll, solvent, water, anhydrous - long to exchange.
Laser printing is an electrostatic digital printing process.
It produces high-quality text and graphics (and moderate-quality photographs) by repeatedly passing a laser beam back and forth over a negatively charged cylinder called a "drum" to define a differentially charged image.1 The drum then selectively collects electrically charged powdered ink (toner), and transfers the image to paper, which is then heated in order to permanently fuse the text, imagery, or both.As with digital photocopiers, laser printers employ a xerographic printing process.
However, 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.Źródło: https://en.wikipedia.org/wiki/Laser_printing
