"My canon MP966 Printer Driver install Problem: O so sad. But my the other computer is upgrade from macos catalina to big sur, the driver is working now. I just wonder why clean install it cannot work"

Please Clarify:
So, the printer is working on another computer, but no this one. Is that correct? And on this computer you want have done new install, but it is not working. Is that correct?
Try the Same Drivers:
If you are looking to do a clean install, and get access to the printer, then try the drivers on this new install, or share the printer. There's lots more you could try like using a new administrator (to troubleshooting an install). But be sure to Create a Time Machine backup of your Mac, so that you can have something to restore your Mac from, should anything go wrong with the driver install.
