I have a Canon Pixma pro-1 photo printer that will shortly become available.
This a pretty high-end photo printer that will print up to A3+ (329mm x 483mm). I'm ready to upgrade my Mac OS X, but unfortunately, Canon have decided they can't be bothered to make drivers for Mac OS X versions thus turning what was an expensive and fully functional printer into a brick/doorstop. Catalina is the last version of mac OS X that will work with this printer. As for Windows, I have no idea. It will mostly be empty of ink when I decommission it. A full set of ink is around £250.
If you're interested, let me know. I can't say for sure when it will be available, depends when the ink runs out.
Keep trying to see if Canon makes OS X drivers. My MG3600 was not listed post-Catalina but I have now found Monterey drivers.
