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.

Laser printing in Wikipedia
Laser printing is an electrostatic digital printing process.
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
What would a company be without business cards, leaflets or other printed articles? Well - the role of the printing industry on the market is still very large, and recently more and more. After all, it's hard for an enterprise that does not have its own leaflets or posters. These companies often outdo each other in offers and offer lower and lower prices, mainly for small businesses.
This does not mean that it is a failing industry, there is still a lot of potential in the printing companies and those that provide them with materials.
Now, the printing services are so accessible that even one-man companies can easily afford to regularly buy printed materials.
Print - definitionPrinting? multiple reflection of an image from a printing form onto a printing substrate (e.g., on paper).
Every copy, that is a print, is commonly called a print.
The printing also means various techniques for copying text and graphics using traditional methods, using printing machines, as well as modern computer methods with the use of computer peripherals, such as printers, plotters, etc. - although such prints should be called printouts.
The introduction of computer techniques and digital printing to printers has meant that printing is also often understood as printing done on an industrial scale by means of adapted printing machines.
