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 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)
It must be admitted that a high-efficiency store's ability to serve customers is not such a difficult task, because it is enough to hire the right number of employees and equip them with the highest quality equipment so that they can sell at a satisfactory pace.
However, the experience possessed by such salesmen allows for specialist support for print shops.
