Printouts made using this type of printers have vivid and clear colors, which is why they are bought by the most specialized photocopying and printing facilities.Such service outlets make a large number of printouts every day, and therefore their owners want to be sure that their devices will not cause any problems during their tasks.
I must admit that inkjet printers give them a lot of pleasure and they become the best advertisers of this kind of printers by ordering more and more of them.They look for different models and additional accessories.
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
Not to mention the much larger range of techniques used, which have nothing to do with those we know from home printers.
