Just installed Big Sur on my Mac mini 2018.
Tried to print to a Canon Image Class MF 4150 and then to a Brother HL-L2360D printers to no avail.
Had to RESET the Mac printing system to solve a problem.
As directed in Apple Support: https://support.apple.com/en-ca/guide/mac-help/mh14001/mac
If you can’t print to your printer and you’ve tried all other solutions, reset the printing system. This process deletes all printers from your list of printers, deletes information about all completed print jobs, and deletes all printer presets.
Important: First, try other troubleshooting techniques in Solve printing problems on Mac.
- On your Mac, choose Apple menu > System Preferences, then click Printers & Scanners.
- Press and hold the Control key as you click in the list at the left, then choose “Reset printing system” from the menu that appears.
- After you reset the printing system, the list of printers in Printers & Scanners preferences is empty.
- Re-add any printers.
