Update.
I upgraded two days ago from my 2013 Mac Pro to a Mac Mini M4 Pro, which means I went from Monterey to Sequoia 15.1.
I downloaded the latest driver for my Canon Pro 4100 (29.1.0.0.) and, to my great surprise, the presets were all there!
The only problem was that the media settings did not "stick" when you made the print. It simply defaulted to "Plain Paper".
Restarting the computer solved that problemLast night I upgraded to IOS 15.2 and tried printing without changing anything. The colours were wrong!
I deleted the printer from "System Settings", re-downloaded the same driver and made a test print - colours wrong!
The media settings were not "sticking" again!
I restarted the computer and everything is back to normal with good colours.
I hope that helps someone...
