Definition of laser printing
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.

Multi-colored prints
The specificity of color printouts lies in the fact that they must be made using the highest quality inks and toners. Otherwise, they will not make a good impression on customers coming to the photocopier and they will just quickly fade. Meanwhile, the use of colored inks often saves important tables or the most important statements appearing in books. Therefore, all people who make color prints want to use multi-colored inks that perfectly reproduce the color of the document to be printed. This is of course very important, but it is equally important to reach for suitable printer paper before making color prints.
Jobs performed by printers
Various types of printers are available for sale. Currently, only printers without scanners and additional accessories are less and less sold. However, this kind of printing devices are most often bought by private individuals who want to print only basic documents, applications or home-made essays written in secondary schools. However, printers can also successfully perform much more complex functions and tasks. With a modern printing device, you can print entire books, color documents and specialized files that require an individual approach. It can be seen that it is worth having a small printer at home and using photocopying services.
