Jiri Adamek provided the answer in another thread and I thought I'd share it here for others to see! I followed the instructions and it solved the problem. SO, it seems that the driver was at fault, and I apologize to Doug for my intransigence. I'm happy to have the problem solved!
Try to download drivers for the printer MF9280 which has newer version of build (v20.85). This drivers must be installed manually from the Control Panel. Do not use Canon setup file.

After it's done, go back to printer Properties, Advanced tab and select right drivers for your printer.
With MF9280 drivers the printer will not work, but in my case old drivers for Canon have begun working. It seems that some component of old drivers was replaced with newer version during setup.
