That's the odd thing, CUPS is (supposed to be) using the gutenprint driver. Here's a list of the relevant packages: kestrel:/home/mike% pkg_info -Ix cups gutenprint cups-base-1.3.7_2 Common UNIX Printing System cups-pstoraster-8.15.4_1 Postscript interpreter for CUPS printing to non-PS printers gimp-gutenprint-5.1.7 GutenPrint Printer Driver gutenprint-5.1.7 The "meta-port" for GutenPrint gutenprint-base-5.1.7 GutenPrint Printer Driver gutenprint-cups-5.1.7_2 GutenPrint Printer Driver gutenprint-ijs-5.1.7 GutenPrint Printer Driver libgnomecups-0.2.3,1 Support library for gnome cups admistration 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. 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. -- Mike Clarke
