Hello, and welcome to the Canon Community!
I'm sorry you're having difficulty getting your printer to do what you expect. More often than not, I hear about this specific issue happening when using AirPrint instead of the Canon drivers and software. I'd recommend installing or reinstalling the software suite to see if it resolves the problem. You can get it from the following shortcut link to the setup utility on our site: https://canon.us/g7020setup
Once you've completed the installation or re-installation, let us know if you still have problems!
