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.
Laser printing in Wikipedia
Ink cartridge Epson
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
Home and Professional Printers
Who today does not have a printer at home.
Their prices are becoming more affordable and operating costs lower.
Multifunction devices offer increasingly larger scanning resolutions, less margin, larger formats, etc.
But still, such home printers are far behind the professional equipment used in professional printers.
Not to mention the much larger range of techniques used, which have nothing to do with those we know from home printers.
Printed roll, solvent, water, anhydrous - long to exchange.
The quality of such printouts is higher, which entails the obvious higher costs of printing itself.
