I've noticed that when printing colour documents, that the colours tend to be very weak (poor saturation). As an experiment, I printed a document from my notebook computer, running SuSE 9.2, via cups to my desktop system (SuSE 9.0). The colours were all washed out. I then printed the same document, from the notebook, running XP and the colours were fine. When I print from my desktop system, the colours are again washed out. In all cases the application was Mozilla, but it the problem occurs with printing from any app in Linux. Given that XP had no problem printing the colours, I think I can rule out both my printer (Canon S600) and cups as the source of the problem. Since the problem is not confined to Mozilla, I doubt that it's the cause. Is there any way to adjust the colour saturation? I use kprinter on both Linux systems.
Look in the ppd - /etc/cups/ppd/yourprintername.ppd - and see if there's anything in there labeled saturation or similar. You can probably also configure stuff from onf of the printer configuration dialogs, like the printers in KDE's control panel, or the gnome printer thingie (gnome-cups-manager?). --Danny, who just hand-edits the ppd, due to some problem with GUI configuration :)
