Specialist company printers
Multifunctional company printers do not have to be large in size so that you can use them to do a lot of really professional looking printouts. Therefore, the largest companies have both small printers and large printing devices used when printing the most important reports and large banners or advertisements. Such printers should always be very durable and truly specialized, because otherwise you will not be able to execute company orders using them. However, having the highest quality printers means that all office work is carried out very smoothly.
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.

Printers tasks
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.
