why are mouse and keyboard and scanner an input device and printer and monitor an output device? Because while a mouse, keyboard and scanner send information to the computer with no information being received back from the computer an output device like printer and monitor get information from the computer without giving the computer any input.

Scanners can only be used as an input device. They scan the image placed inside/ontop and digitalise it and display it on your computer screen. The only type of scanner that can output is an "all-in-one" scanner/printer that can print out the images you scan in or other images from your PC, but that is not technically a scanner, it is a scanner, printer combination. So no, Scanners can only be used as input devices.
