Some programs can't find printers
I'm running Fedora 15, x86_64, xfce gui on top of metacity.
Before I upgraded from Fedora 14, I could use several printers.
1. Now, when I open the print dialog, no printers show up from inside Firefox, Thunderbird, gnucash, f-spot, opera, planner, eclipse.
2. The printers ARE recognized inside Adobe acroread, bash/tcsh command line, libreoffice, openoffice, frescobaldi, gedit, evolution, gwenview, okular
3. Gimp is sort of in the middle. It doesn't show any printers in the print dialog, but I can print in only black & white via Gutenprint.
If you have lpstat, try
Hope this helps some.
1. CUPS shows the printers as present and accepting requests.
2. Same for lpstat
% lpstat -a

3. Some applications recognize the printers and can print just fine. (See item #2 in my initial posting, above.)
4. Some applications recognize none of the printers, and therefore, cannot print at all. (See item #1 in my initial posting, above.)
Because of this divergence, it appears that there are two mechanisms for accessing the printers, and some class of the applications aren't using a working mechanism or the other mechanism broke.
