4 year old printer prints blank or only a couple of words when started from either of my Windows 10 PCs. Print nozzle test however, comes out fine. I've tried updating the driver, reinstalling the driver, resetting the printer, and cleaning the nozzles. Scanner connects with no issues, Can't test the fax function.... but who needs it.

The nozzle check for your PIXMA MX922 should look like this:
Does PGBK print at the top of the nozzle check that you printed from your PIXMA MX922?
