Hello Jim,
Thank you for the report.
I can only speak for the gutenprint driver, although I find it hard to
believe that the Canon driver does not work, since that would be the
official driver provided by the manufacturer. That leads me to think there
might be something else going on.
I believe that the iP90 should work bascially, given the length of time it
has been supported, but there could well be bugs.

Can you set the logging to debug in CUPS, including suiteable maximum log
site (unlimited would be good maybe), and then print using a monochrome
resolution setting (not automatic) and grayscale, on plain media. That
would be the simplest test. You can send me the logfile as a zipped
attachment directly (not to the mailing list).
