Wikipedia definition of printer
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)
Professional support for printers' shops People who come to the store with printers hope that they will be quickly and efficiently and at the same time expertly served. 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.
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.
Printing once and today
Printing is needed, no one has doubts about it, but are they just as necessary as 20 years ago? This is a debatable issue, but certainly the market needs and consumer demand have changed a bit.
The production of marketing materials increased significantly - leaflets, banners, promotional leaflets, and advertisements - and decreased the production of books and magazines, mainly due to the popularization of the Internet. Will we wait for the times when printers, DTP operators and printing house owners will have to look for a new job?
