A printer is a device that transfers data, such as text or images, from a computer to a physical medium, typically paper. It's essentially a piece of hardware that allows users to create physical copies of digital documents or other information.

Function:

Printers create hard copies of digital content.

They can handle various formats, including text, images, graphics, and even 3D objects.

They are often connected to computers and controlled by them, although some printers can operate independently with devices like digital cameras.
