A new release of KUPS , designed for KDE2, is available. It supports a large range of printers through various available drivers and ghostscript.
Drivers are already available for most common printers.
The following comments are owned by whoever posted them. And compatible to the old lpd if you activate the printcap entry. Kups looks nice, even though it seems a little bit unstable at the moment. It will be integrated into KDE2.1 if I recall correctly. It's very usable and stable now.
