Printers

A printer is an electronic external output device that accepts images and text files from the computer or other electrical devices to generate a hard copy (by transferring the files or images to papers). Printers can be connected to the computers either by direct connection or through the internet. A printer is one of the popular peripheral devices, which is used to print documents. A document can contain an image, text, or a combination of both.
