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)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.
Poligrafia and DTP-WorkThe DTP operator is a responsible person in printers, publishing houses and wherever materials are printed in large quantities, for the correct preparation of files that will be printed.
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.
What would be without printing?Everyone likes colorful magazines or leaflets.But what would the world of marketing and advertising look like if it were not for printing and printing? Today, such things are produced on a mass scale, expenditures are increasing, because demand is growing all the time. Nowadays, there is no company that at least once would not use the services of a printing company - leaflets, business cards or a small banner, it's almost a standard for every company.From small ones to big ones? it is known that on a different scale.
However, you can still see badly marked or un-promoted brands, the reason for this may be the lack of investment in printing advertising materials. .
