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)It is true that it has many varieties and uses different techniques and materials (paint, paper). The main division is cold printing, where the paint is fixed by soaking into paper.
Water and waterless - offset printingOffset printing is the most popular type of printing in today's printing industry.
While the 'hot' offset where the printed paper web passes through the drying tunnel. The classic offset (water) is associated with the use of water rollers and hydrophilic and hydrophobic surfaces, however, this method is already abandoned due to the difficulty in obtaining a good balance of water and oil paint. The successor of this method is anhydrous offset printing where silicone molds are used instead of water.
PaperPaper in printing and printing is probably the most important thing next to paints. Without it, printing would not be possible. Paper as a material has been known since 105, n.
E., That is for a very long time.
However, it was not until the twentieth century that more and more types of paper for various applications were invented. And now we have paper chalked, white, slippery, coated with plastics, etc.
All this to achieve different results of advertising and journalistic printing.The end result of the printed item depends on the choice of paper, its durability and durability. .
