I have a "Filter failed" error on mac os 10.14.2 after printer firmware update (1805). I tried to remove/add the printer, reset printing system, verify and repair mac permissions, fully uninstall and install HP easy start package, delete files in Library > Printers > HP, delete Library > Printers> PPDs > Contents > Resources. I connected the printer to WIN7 PC, and the printer is works fine, but on my mac it not work now.
