Which printer/scanner is compatible with 13 inch MacBook Air?

So very many printers and scanners are compatible with your Mac.

For the sake of ease of setup and use, I suggest that you focus on devices that are AirPrint compatible. There are lots! AirPrint compatible printers will not require drivers from the manufacturer that must be kept updated and may break when new versions of the OS are installed.
