The printer is an auxiliary object, which is connected to a central processing unit of a computer, its function is to make a copy of those documents that have been stored in an electronic format. These documents can be texts or images that are printed on a sheet or transparency using ink cartridges or laser technology.
Most printers are linked to a computer by means of a cable, although there are also network printers, which have an internal network interface, which allows any user on the network to print documents.
Some of the characteristics that we have of the printers are: the printing speed which is determined in pages per minute (ppm) or in characters per second (cps), the resolution that refers to the quality of the printing and is expressed by the amount of points (pixels) that the printer can create on the paper, the memory buffer (temporary data storage area in the printer), connection interface, cartridges, built-in memory and finally we have the paper.
Each printer has specific printing methods, because there are different technologies, in terms of image quality, printing speed, cost, noise, internal and external design; This makes each printer different, among the types of printers we have those of toner, inkjet, solid ink, impact, dot matrix, dye sublimation.
In addition to the aforementioned printers, nowadays new technologies have emerged that lead us to braille type, line and 3D type printers that allow having a copy of the document in 3D, and finally multifunctional printers that not only You can print but photocopies are also made, and in some cases it is possible to send faxes.
