I've just connected an Epson Photo 890 to my Fujitsu running VL6.0, and used CUPS to install it no problem. As far as printing goes it's working OK.
However, it's clear the print heads need cleaning. When I go to the CUPs page and click on 'Manage Printers', and 'Clean Print Heads', I get the following error message:
Epson "/usr/lib/cups/filter/pstoraster failed"
How do I get round this?
