For me it looks like that some model-specific plug-in or configuration file is called by the pstocanonbj filter but this file is missing. ave you installed all parts of the driver (there is perhaps one general and one model-specific, or one with the open-source parts and one with the closed-source part)?
Is your printer model explicitly supported by the driver? This is most probably not a Ubuntu bug but a problem of Canon's driver. -- Canon MP500 won't print https://launchpad.net/bugs/73166 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
