gedit seems to suffer from a similar bug as bug #219132 (evince).

Description of problem:
When a printer is marked as rejecting jobs with the CUPS 'reject' command, the
GTK+ print dialog will not display that queue any differently -- it will appear
as though it is fine to print to it.

Even worse, when the job is actually submitted there is no error given to the
user, so they think their job is submitted but it isn't.  Even with
'PreserveJobFiles On' in /etc/cups/cupsd.conf, the job will be lost forever.

Version-Release number of selected component (if applicable):
gedit-2.15.9-1.fc6

How reproducible:
100%

Steps to Reproduce:
Start with a queue named 'stylus'
1.reject stylus
2.Start gedit and type a text document
3.Ctrl-P, and select printer 'stylus'
4.Click Print
  
Actual results:
Job appears to get submitted, but is in fact lost forever.

Expected results:
Error message, or else it isn't possible for the user to attempt to submit jobs
to a printer not accepting requests.

Additional information:
OpenOffice.org Writer for example at least says that the print failed.
