Trouble-shooting

Monday, February 4th, 2008

I’ve added a simple trouble-shooting mode to system-config-printer in version 0.7.80.  It’s not very sophisticated, but I hope it will be useful.  It is a “wizard”-type dialog with forward and back buttons, and the Python source code allows for question screens to be slotted in fairly easily.  If it can’t work out the problem it will display some diagnostics that could be useful to attach to a bug report.

To try it out, hit F1 or select Help->Troubleshoot from the menu.
