installation problems

Yast hangs during printer installation (Suse Linux 9.1 and 9.2)

Using Suse Linux 9.1 and 9.2, I had for a long time problems with installing additional printers using Yast2. Since I had free installation support for 9.1 I contacted Suse, but to no avail. Printer installation is not covered by the free installation support. The advice they gave me was trivial and did not work (uninstall CUPS and reinstall it again). Additionally most of the installed printers were stopped (a red cross over the printer icons under Start Menu > Utilities > Printing > Printing Manager) and could not be started again.
