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
This is very important because this type of printing device is very often used by women and young people who would not be able to carry heavy printers on their own.Just using them is not a problem for them, because home printers are designed in such a way that they are fully intuitive and work perfectly with computers and laptops.
Their service is therefore a real pleasure and allows you to prepare various types of tasks and statements, as well as reports and speeches.
All this makes it really worth having small printers at home.
