Laser printing in Wikipedia
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.

Generally print
Printing? 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.
Broad polygraphy
The printing itself is a department wide as the sea and various fishes in this sea are swimming. From simple leaflets to large banners or window stickers. With such a broad concept, it is sometimes difficult to say what the printing company specializes in.
Some factories are choosing low-volume small-format prints, others for stickers, and others only for large-format printing. What sometimes makes it difficult to choose one plant for our orders, but what the market is like, and the price of services and their quality are also important.
