TCP network printer with CUPS
I had a network printer working from my linux machine using CUPS. However, it stopped working. After trying various things, I removed the printer using the KDE (3.2) printing wizard and tried adding a new printer. When it comes to printer backend selection, the "tcp" option is greyed out, meaning it is "not available". Why would the tcp option disappear? What components do I need to have installed so that CUPS and/or KDE knows "tcp" is an option?
For further information, this is a Debian/unstable desktop PC running KDE 3.2.1. I thought I might have broken something with an "apt-get upgrade", but the machine has been running some time with no problems and I frequently update/upgrade software. I have no idea where to start looking for the source of the problem. The cups packages are properly installed with all dependencies.
