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.
The first computer printer designed was a mechanically driven apparatus by Charles Babbage for his difference engine in the 19th century; however, his mechanical printer design was not built until 2000.
This enables laser printing to copy images more quickly than most photocopiers.Źródło: https://en.wikipedia.org/wiki/Laser_printing
Printer - Wikipedia definition
In computing, a printer is a peripheral device which makes a persistent human-readable representation of graphics or text on paper.
The first electronic printer was the EP-101, invented by Japanese company Epson and released in 1968.
The first commercial printers generally used mechanisms from electric typewriters and Teletype machines.
The demand for higher speed led to the development of new systems specifically for computer use.
In the 1980s were daisy wheel systems similar to typewriters, line printers that produced similar output but at much higher speed, and dot matrix systems that could mix text and graphics but produced relatively low-quality output.
The plotter was used for those requiring high quality line art like blueprints.Źródło: https://en.wikipedia.org/wiki/Printer_(computing)
Internet printing Online printers are gaining more and more supporters, not surprisingly when more and more commerce is done online.
This is a very convenient solution, because you can immediately overcome mistakes made by potential customers when placing an order.
Often, they send a bad file in the wrong format, with the web printing this error is still captured by the script itself accepting the order.
Of course, such printers also have their drawbacks, ie the lack of the possibility of an individualized approach to the client and his needs, unless we get a really good printing house.
