Hi Harveydad!
Welcome to the Canon Forums and thanks for your post!
So that the Community can help you better, we will need to know any error messages you might be seeing, and the the exact version of the Mac OS you're using, as well as the way you connect to your printer (USB or networked via WiFi or Ethernet).
Any other details you'd like to give will only help the Community better understand your issue!
If this is an urgent support need, please CLICK HERE to reach our friendly Technical Support Team during normal business hours by phone or anytime by email.
Thanks and have a great day!
