I’ve previously been able to print on a network Konica Minolta Bizhub C450i printer from Ubuntu 20.04
After switching to Fedora 38 I’m getting ‘Filter failed’ when trying to print a test-page (as evident from localhost cups webpage).
I have installed the drivers as downloaded from the Konica Minoltas webpage (bizhub c450i) using the provided install.pl script – the drivers now reside in /usr/share/cups/model (KMbeuC650iux.ppd) and the filters reside in /usr/lib/cups/filter (KMbeuEmpPS.pl and KMbeuEnc.pm). I have ensured that the two filters have read and execute permissions (chmod 755).
I have restarted the cups server. I have rebooted. I have re-installed the printer.
Still no luck – don’t know where to look next. Any suggestions?
