Ive found that some people got it working with Big Sur
But no one said how they solved it or what they did?
Here is a thread/topic about it: https://discussions.apple.com/thread/252548412?answerId=252548412021#252548412021
Im trying to help a friend that have this old printer and cant get it working with her new computer running Big Sur.
No, its not a scanner, its a inkjet photo printer! Nothing else.
If this is really the CanoScan 9000F Mark II scanner, then the optional, paid, VueScan Professional scanning software supports this scanner on macOS without any Canon or Apple application/driver support. There is a free downloadable trial.
In 2010, I had an old Canon flatbed scanner that they had dropped support, and I purchased VueScan Professional to support it. That scanner with the current VueScan software works on macOS Monterey 12.0.1. In the ensuing eleven years, I have never had this scanner fail to work on any release of macOS and have never paid any update/upgrade fee to the VueScan vendor. I receive nothing in return for mentioning the product here.
For those needing a USB-A to USB-C connector for newer Apple products, Apple provides one here.
Canon Pixma Pro 9000 Mark II, Big Sur, Not working.
