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
In some situations, you can also use the free delivery option for printer inks and thus introduce home savings or reduce office maintenance costs.It must be admitted, therefore, that people who conduct printing activities longer know very well, in which stores special discounts for the purchase of printer inks are introduced.
