This is one of many XPS driver bugs. Do not use the XPS driver for your Canon printer and use the regular (non-XPS) driver instead. The XPS drivers simply don't work outside of Canon's own printing software.

So if I actually try to print, the portion outside the Qimage window will not print?
I have not been able to use the printer to print for at least six months, and was taking one final try before dumping the printer. A print on letter size paper printed great yesterday. I guess I will have to see if I still have the older driver installed on my wife’s Win 10 laptop.
Part of the problem started when the Canon drivers on my iMac failed when I did the upgrade to macOS Mohave, when I checked with Canon they confirmed that the Driver for the printer would not be updated.
