Appeared in: UPPSC 2017

Explanation

A printer is an output device, as its primary function is to take processed digital information from a computer and create a physical copy (output).
Input devices send data to the computer, whereas output devices receive data from the computer.
The printer does not send data to the computer for processing; it presents the final processed data to the user.
Examples of output include printing patient records, lab results, or educational materials.

Option B: A mouse is a standard input device used for pointing, clicking, and navigating a graphical user interface.
Option C: A keyboard is a primary input device used for entering text, numbers, and commands into the computer.
Option D: A microphone is an input device that captures audio and sends it to the computer for processing, recording, or transmission.
