My school's tech team recently updated my MacBook Pro to Big Sur. In the process, I seem to have lost the ability to print from my home computer, Canon MP190. How do I access a software update that will enable me to print from my home printer again?
If it is listed as AirPrint printer, delete the existing printer in
> System Preferences> Printers & Scanners, and add it again, select AirPrint.
Connect an AirPrint printer to a Wi-Fi network - Apple Support.
