How to install printer software on my MacBook Air m1 2020

Hi,

You may not even have to install printer software. Any information about the printer model you have in mind? An AirPrint-enabled model is compatible with macOS, and does not need additional drivers, provided that the printer and the computer are connected to the same network (Wi-Fi router).
