I was afraid that might happen. It needs a specific filter program. I'm assuming that pstocanonij is a binary-only Linux program?

Gimp uses Gutenprint doesn't it? So you could try using the gutenprint driv= er? My strategy is to try and avoid these troubles. Spend a bit more and get a printer that works with postscript. Those will work on any UNIX-like OS.
