Hi Linda333!
So that the Community can help you better, we will need to know exactly what Canon printer you're using (the model information from the top/front of the printer, not from your computer), any error messages you're seeing, and the Computer Operating System you're using (Windows Vista/7/8/10 or macOS 10.x), 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 call 1-800-OK-CANON (800-652-2666) to reach our friendly Technical Support Team by phone weekdays from 10am to 10pm (ET).
If you're outside of the USA, you'll want to reach out to Canon in your country by clicking HERE.
Thanks and have a great day!
