Standards in print and not only
Standards in every industry and business are important. Imagine that we buy a monitor and its input does not match our video card, even though it has the same type. That's why certain standards apply.
In polygraphy and graphics, such standards also exist - appropriate definitions of CMYK colors - key for the appropriate color reproduction. Specified in advance formats for printing leaflets and business cards, so that they are comfortable and as uniform as possible. Without standards, even leaflets could be completely unreadable and even repulsive.
Even the highest quality printing device can fail, especially when it is used every day for many hours. Therefore, a professional printer service is a type of service that enjoys great interest, and people who are well-versed in the repair of printing devices can count on having a large number of satisfied customers. The same applies to professionals involved in the replacement of parts in printers or the installation of suitable replacements. They can provide their services in their showrooms or commute to clients. This means that the services they provide are at the highest level and are often ordered by owners of various types of printing devices.
Printer - Wikipedia definition
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.
