In computing, a printer is a peripheral device which makes a persistent human-readable representation of graphics or text on paper.
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.
The plotter was used for those requiring high quality line art like blueprints.Źródło: https://en.wikipedia.org/wiki/Printer_(computing)
The task is easy and simple in theory, however, one small error of the DTP operator and the circulation of several thousand copies of newspapers can be thrown away.In this work, many things may go wrong: change of paper for another, new printer with other inks, incorrect conversion of colors. There are also typo errors, bad placement of some element or just a few details. All this can end very badly and bring big losses - so it's work under stress and tension, because if something goes wrong it usually will be just for the DTP operator.
I must admit that inkjet printers give them a lot of pleasure and they become the best advertisers of this kind of printers by ordering more and more of them.They look for different models and additional accessories. .
