I actually ran into a set of broken printing on another system yesterday, a canon pixma m920 … I couldnt investigate fully, but it may have had nothing to do with the device or drivers, as I attempted re-adding multiple ways (gutenprint, driverless, cijfilter, etc)… but printing failed on all attempts, either from ‘cannot locate printer’ or some other pstopdf/ghostscript ‘exited’ non-error without printing.
Sorry to not be of more help just now. But I might be back
