I've just installed a Canon Pixma iP4500 on a 6.3 system using CUPS and gutenprint. Black printing is fine but I've got problems with colours. The colour wheel on the CUPS test page comes out as a psychedelic collection of brightly coloured rings. If I print from gimp then the correct colours appear but they are very dark and "muddy". The colours start to look a bit more reasonable from the gimp if I push the gamma value up to 2. This isn't a physical problem with the printer, I get good results when printing from Windows. Should I be able to get correct colour rendering "out of the box" or do I have to fiddle about with the multitude of output control adjustments available on the CUPS admin panel? Or should I be using something other than CUPS, that's what I've always used so far but I'm happy to try alternatives if necessary. -- Mike Clarke
