How can I fix this error so my printer can print?

You're going to need to provide much more information.  How is anyone supposed to figure out what printer you are using, with what computer (Mac? PC?) or device (iPhone?), what operating system, and what error code?

Thanks for joining the conversation, Nora1222!

So that the Community can help you better, we need to know exactly which Canon printer model you're using, the computer OS you are using, and the error code/message that is being displayed. That, and any other details you'd like to give will help the Community better understand your issue!
