Printer 'filter failed' in Mojave
Upgraded to Mojave and my HP LaserJet CP1025nw printer never works.
Reset printer system several times and reinstall HP printer driver v5.1 pack, but no luck.
It's always got 'filter failed' when printing doc/photo files with Preview app.
Finally I found it's APPLE's problems and not HP's driver issues.
'Preview' app can't print PDF files and 'Foxit Reader' app can print PDF successfully.
Hope Apple can check this issue and fix it as soon as possible. Thanks.
macOS Mojave (10.14.1)
