Printing? multiple reflection of an image from a printing form onto a printing substrate (e.g., on paper). Every copy, that is a print, is commonly called a print.
The printing also means various techniques for copying text and graphics using traditional methods, using printing machines, as well as modern computer methods with the use of computer peripherals, such as printers, plotters, etc. - although such prints should be called printouts.
The introduction of computer techniques and digital printing to printers has meant that printing is also often understood as printing done on an industrial scale by means of adapted printing machines.
Specialist company printers
Multifunctional company printers do not have to be large in size so that you can use them to do a lot of really professional looking printouts. Therefore, the largest companies have both small printers and large printing devices used when printing the most important reports and large banners or advertisements. Such printers should always be very durable and truly specialized, because otherwise you will not be able to execute company orders using them. However, having the highest quality printers means that all office work is carried out very smoothly.
About printing companies
Paints, inks, paper, toners, foils and other consumables - these are things that can not be missing from printing plants. They are ordered wholesale and also consumed in bulk. For each order, the production costs are optimized, and the appropriate technique and type of printing is selected.
Graphic designers, DTP operators and printers deal with this. They are responsible for the quality of the printout and as soon as something is wrong they are the first to be targeted by the dissatisfied boss. Their work is quite hard and I have to admit that you have to really have a fuss to do it. Work after hours, maximum focus and responsibility - definitely not work for everyone.
