Which type of peripheral device produces printed output on paper?

A printer is the peripheral device specifically designed to produce printed output on paper. It takes digital information from a computer or other digital source and translates it into a physical copy on paper, allowing users to create hard copies of documents, images, and other data. Printers can vary in technology, including inkjet, laser, and dot matrix, each serving the same fundamental purpose of converting digital data into a print format.

In contrast, a monitor serves as a visual display device that presents digital content but does not create physical copies. A projector, while useful for displaying content on a larger screen, also does not produce paper output but rather shares information via a visual medium. A scanner is used to digitize physical documents or images, converting them into digital formats for storage or editing, rather than producing printed output. Thus, the function of each of these devices is distinct, with the printer being uniquely designed for the task of printing on paper.
