All, Linux printing has always just worked for my Laserjets. I have a remote cups server that handles sending print jobs to an attached printer. This has been a great setup. In 15.4, I had no problem printing from any app, Gtk, Qt/KDE, command-line, it all worked. In Tumbleweed, I copied my /etc/printcap file from 15.4, e.g. $ cat /etc/printcap # This file was automatically generated by cupsd(8) from the # /etc/cups/printers.conf file. All changes to this file # will be lost.

KDE3 kprinter is fine printing to the LaserJet, but Gtk apps (LibreOffice, Firefox) cannot print. The lpq command is happy with the print queue: # lpq LaserJet is ready no entries But attempting to print from LibreOffice throws the error: "Could not start printer. Please check your printer configuration." What? I've just checked it all, it's good, why won't Libre of Firefox (Gtk apps) print? What configuration is it telling me to check? CUPS, Yast and kprinter are all happy? -- David C. Rankin, J.D.,P.E.
