You may need Gutenprint, a printer driver for Linux (http://gimp-print.sourceforge.net/
). But I'm not sure if they have one for that particular printer yet. You can ask if they can support it.
I did a little looking around and found info on this page: http://forums.linux-foundation.org/read.php?25,9006
(I hope the link works alright). According to that info, you can get a driver right from Canon themselves (Canon Europe). Just read about it on that page I gave you the link for. I hope this helps.
