Hi! My name is ***** ***** I'm happy to help!
What is the version of OS on your Mac?
I'm looking into it. Standby.
Try downloading a fresh driver and see if that works. CLICK HERE to access the Canon website and click Drivers and Downloads. Under operating system choose your OS version, then click download on the CUPS printer driver. Install it and let me know what happens afterward.
Did you reinstall the driver per my original answer?
