I recently upgraded from F29 KDE to F30 KDE and after this update printing stopped.
I have 2 network printers installed, one Ricoh MP C3003 and one Epson L550. On F29 everything worked, after the upgrade it stopped.
When I try to print any of the installed printers, I get the same error: filter failed, see the attached picture.
Do you have any idea, to solve the problem?
