[Gimp-print-devel] Help/testing offer for Canon PIXMA MG8220

[Andrew M. <and...@gm...>]

I've just acquired this printer. Sending JPEG with lp -o raw produces a
borderless photo, and PS/PDF via gutenprint works, but gimp and photoprint
both produce a job in the local CUPS queue and cause the printer to
indicate that it's receiving data, but end without any print or any
indication of error. Results are similar whether using dnssd/ipp or bjnp.
Is there more I can do to diagnose the problem? And is there anything else
specific that I can test?

The ink selection is a little odd, too. In gimp and photoprint, CMYKk only
seems to be available for the hagaki quality settings - it seems odd both
that high and photo settings don't use the gray ink, and that quality
settings refer to a media format at all. Am I missing something here? On a
related note, do color documents use the pigment ink for solid black, or
can I only use it with the "black" ink setting?
