A printer is a hardware output device that accepts text and graphic output from a computer and transfers the information to paper, usually to standard-size, 8.5" by 11" sheets of paper. Printers can print any information that has been passed to it, whether it be text, numbers, or images. There are different types of printers, including:
-
Inkjet Printers: These printers recreate a digital image by spraying ink onto paper. They are the most common type of personal printer.
-
Laser Printers: These printers use a laser beam reflected from a mirror to attract ink (called toner) to selected paper areas as a sheet rolls over a drum. They are commonly used in offices.
-
Dot Matrix Printers: These printers work with paper via direct contact with an ink ribbon. They have similar mechanisms as typewriters.
-
3D Printers: These printers are used to create three-dimensional physical objects from a 3D model or other electronic data source through additive processes in which successive layers of material are laid down under computer control).
Printers can be connected directly to a computer or indirectly via a network. They are one of the most popular computer peripherals and print text and photos. The benefits and uses of a printer depend on the type of printer. For example, 3D printers can be used to print tools or parts needed to build something, while inkjet printers are commonly used for personal printing needs.
