A bit more difficult task may be to create an advisory base for clients who are not sure what kind of goods they want to buy.
However, the experience possessed by such salesmen allows for specialist support for print shops.
Thanks to them, all clients will receive the information they need.
Therefore, a professional printer service is a type of service that enjoys great interest, and people who are well-versed in the repair of printing devices can count on having a large number of satisfied customers.

In computing, a printer is a peripheral device which makes a persistent human-readable representation of graphics or text on paper.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. 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).
