Description Tim Waugh 2011-10-06 11:42:02 UTC

Description of problem:
With the Printers settings window open, disconnecting a connected printer does not show any effect even though the CUPS queue has been paused.

Reloading it by clicking All Settings and then Printers shows it correctly: the list item is shown "greyed" and the on-off widget is set to OFF.

Reconnecting the printer does correctly update the window.

Version-Release number of selected component (if applicable):
control-center-3.2.0-1.fc16.x86_64

How reproducible:
100%

Steps to Reproduce:
1.Plug in printer
2.System Settings -> Printers
3.Disconnect printer
  
Actual results:
No change shown in the window

Expected results:
New printer state should be shown.

Hi,

I've just committed a fix for this into upstream's git. It will be available in gnome-control-center-3.2.2 release (which should be available at 16th of November).
The problem here was that the panel was not connected to CUPS' event "printer-stopped". But it have been connected to "printer-state-changed" and this is strange because the printer changes state when unplugged but CUPS doesn't emit "printer-state-changed" for that, just the "printer-stopped".

Isn't this a bug in CUPS?

Regards

Marek

Thanks.

No, this seems to be according to how RFC 3995 says it should work (ref. 5.3.3.5.1).
