Cups, canon printer and error

Hi, I'm working on enabling a Canon TR 4500 printer in Crux. Have a package mostly done. Cups server recognizes printer and finds ppd files. Now, I have a problem with printing test page. Cups page shows: stopped "Filter failed" I'm attaching error message. Any suggestions?
