How to install Canon printer with Big Sur

i had the same problem, I could print not scan, please review my answer, it is a macos firewall problem

Try the demo version of VueScan. It supports nearly every scanner made. Its website will have a list of supported scanners.

Brilliant - but how do I "add those apps to the firewall". I'm over 50 so therefore ignorant to the mechanisations of the technical aspects of everything!

SYSTEM_VERSION_COMPAT=1 from xSashaCH worked for me. After install of a High Sierra ICA driver for my MG6250 multifunction, scanner was available in the Image Capture app under Big Sur. Thanks!

Wow! thanks! It's working now with the version for ElCapitan.

The problem seems to not be fixed even now, but with this older version everything is okay, I am printing right now.

canon lab 2900 B driver is not working on my Mac Big Sur M1?

OK, Gutenprint is still a go. It appears just the webpage is stale, the software works perfectly on Big Sur.

I am printing now. Thanks.

This solution worked immediately. Thanks for the help.

Thank you so much, Gutenprint worked for me! I was not able to print with my Cannon after updating my OS and getting a new Mac. I hope someone else who needs this finds it.

I FIGURED IT OUT!!!!!!

Canon don’t seem to be supporting older printers with drivers but if it’s a wireless printer you can use it via the Canon printer Selphy app. I don’t print much & it works ok on my MP560, so far.

This helped me as well. Thank you
