The printer is one of the peripherals that can be connected to the PC or the Notebook and through which one can obtain a copy, or several, of those documents stored in the equipment, either texts or images, since it prints them in paper or transparencies using ink cartridges or laser technology.
Mostly and as we said, a printer is connected by a cable, as a peripheral to a computer permanently, however, also, a printer, through an internal network interface, Ethernet or Wireless, the so-called network printer, it will allow any user on the network to print any document from their computer even if the printer is not directly connected to their computer. This situation turns out to be frequent to observe in offices, in which the constant need to print documents is recurrent and then, to lower costs and because not also reduce the amount of peripherals if spaces are not abundant, this type of solution is the ideal.
Nowadays and as a consequence of the incredible advances that have occurred in computing, it is possible to find printers that in addition to printing documents allow different multimedia electronic devices to be connected to it, such as Pendrives, Compact Flash, digital cameras, scanners, among others. There are even some printers that, in addition to their traditional printing function, offer other functions such as scanning and faxing, becoming almost, almost a copy machine.
Traditionally, printers have been slow devices, that is, they do not allow a considerable printing of pages per minute, for example, 10 pages per minute turns out to be the fastest, that is why when it is required to print in quantity, the most usual is take the job to a printing company that has large machines that can print hundreds of pages per minute.
Among the types of printers that we can find are: monochrome, color and photographs, which allow you to print photos with incredible quality and resolution.
Meanwhile, there are various printing methods, the traditional one is the toner, which are used by most laser and thermal printers. They use the principle of Xerography: a toner adheres to a printing drum that is sensitive to light and static electricity transfers the toner to the printing medium. Those of Ink Jet ink On the other hand, they spray very small amounts of ink onto the printing medium. And finally there are those of solid ink (the ink is melted and distributed through a greased drum), Impact (they work with a head composed of needles, which hit a ribbon, similar to the method of typewriters), dot matrix (It is of the impact type but unlike this it uses very small pins to create precise points), dye sublimation (uses heat to transfer ink to plastic, paper, or canvas media).
