Gimp uses Gutenprint doesn't it? So you could try using the

That's the odd thing, CUPS is (supposed to be) using the gutenprint
driver. Here's a list of the relevant packages:

With my previous (non-postscript) LaserJet 6L printer, there were two drivers I
could use, IIRC. One labeled "LaserJet 6L" and one labeled "LaserJet 6L
(gimp-print)" or something like that.

After a bit of fiddling about with the printer settings for the Gimp I
can get tolerable results when printing from the Gimp, though still not
as good as the Windows drivers give. Printing from any other
application just produces totally wrong psychedelic colours. There's an
example showing an original file and a couple of scans of prints at
<http://www.milibyte.co.uk/colours.pdf>. The images have lost some
quality in the scanning but effectively demonstrate what's happening.

It looks like it is rasterizing too coarse.

CUPS is using the ppd file extracted
from /usr/local/share/cups/model/gutenprint/5.1/en_GB/stp-bjc-PIXMA-iP4500.5.1.ppd.gz.
I'll not post the contents here ( > 2000 lines) but there's a copy at
<http://www.milibyte.co.uk/Canon.ppd> if anybody's interested.

I can't spot anything suspicous in that. Maybe you should try a
gutenprint mailing-list/forum.
