I had no problems using my Canon MF4350d printer with Windows 10 for all features. I just bought a nice dell XPS desktop with windows 11 and I will keep my older dell XPS desktop that runs Windows 10 and this printer fine. I didn't see any drivers for windows 11 to use on the new dell so I tried the latest windows 10 drivers but no luck.
If canon doesn't offer windows 11 drivers for my Canon MF4350d printer I can still use it with my older desktop, but I am very disappointed if Canon doesn't fix this issue quickly or provide a reasonable explanation why it is not possible to fix it. I may have to install Windows 10 on my new computer if that's the only way to keep my printer. A pox on both Microsoft and canon for making something as simple as a printer obsolete with this windows change. If no fix, I can't recommend Canon as a company that will be there for customers in the future as they consider their tech products as disposable. I thank God I only have 1 unused cartridge for this printer.
I tried repeatedly downloading/installing Windows 10 drivers without success. I needed to install in compatibility mode. The link below has the detailed walkthrough:
