My operating system: macOS Mojave 10.14.2. My printer is Canon imageclass D420. I never had this issue for the last couple years I've owned this printer. All of a sudden I get a "filter failed" message when I try to print pdf document. So far I've tried going into 'Printers & Scanners' and "resetting printer system" and uninstalling and reinstalling the printer driver. The problem message only appears when I try to print pdf. No issue with printing word doc.
Any suggestion would be appreciated. Thank you.
