Of course, such printers also have their drawbacks, ie the lack of the possibility of an individualized approach to the client and his needs, unless we get a really good printing house.
Their prices are becoming more affordable and operating costs lower.Multifunction devices offer increasingly larger scanning resolutions, less margin, larger formats, etc. But still, such home printers are far behind the professional equipment used in professional printers.
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.
