The problem was indeed caused by the gnome-settings-daemon package. I have attached the debdiff with a workaround which simply suppresses this misleading "Printer XXX may not be connected", triggered whenever CUPS reports "connecting-to-device" which it does on every job. This is a workaround as we are after string/UI freeze. The fix is to improve the text, for example to replace it by "Connecting to printer XXXX ...". The same text improvement should also be done in system-config-printer.

The attachment "Workaround to suppress the "May not be connected" message." of this bug report has been identified as being a patch in the form of a debdiff. The ubuntu-sponsors team has been subscribed to the bug report so that they can review and hopefully sponsor the debdiff. In the event that this is in fact not a patch you can resolve this situation by removing the tag 'patch' from the bug report and editing the attachment so that it is not flagged as a patch. Additionally, if you are member of the ubuntu-sponsors please also unsubscribe the team from this bug report.

This bug was fixed in the package gnome-settings-daemon - 3.1.92-0ubuntu2

---------------
gnome-settings-daemon (3.1.92-0ubuntu2) oneiric; urgency=low

  * debian/patches/45_suppress-printer-may-not-be-connected-notification.patch:
    Do not show notifications if the printer state reason "connecting-to-device"
    is reported by CUPS. The text of this state reason notificatioon is the
    misleading "Printer XXX may not be connected" and the reason is set in
    every print job (usually only for a short time but enough to trigger the
    notifier). As we are after UI freeze we simply suppress this notification
    with this patch (do not forward upstream). The real fix would be improving
    the text, like really saying "Connecting to printer XXX ..." (LP: #842768).

In my reading of the bug above, it appears this is still open because:

 | printer state reason "connecting-to-device"

I don't think this is ready for sponsorship or upload then for P, and am then going to unsubscribe ubuntu-sponsors.
If you disagree, please re-subscribe ubuntu-sponsors.

If I'm right, then feel free to submit a merge proposal or attach a debdiff and re-subscribe sponsors.

The subscription of the ubuntu-sponsors was done by an automatic process triggered by my addition of a debdiff. When I added the debdiff it was already decided that the maintiner of the gnome-settings-daemon, Rodrigo Moya, uploads it for me and he did. So I did not relly notice this subscription dangling around.

I'm using the gnome-fallback session with Ubuntu Precise, as Unity doesn't work with thin clients (LTSP).
The first time I print a job, the notification area shows "Error: connecting-to-device", but printing completes successfully.
This confuses students, which try to send their jobs again, resulting in duplicate prints.

Any plans on fixing this? Where can I help, revise the proposed patch?

In gnome-fallback, both indicator-printers-service and gsd-printer are running as part of the session.

larsu in IRC suggested the following workaround:
> (11:36:40 μμ) larsu: alkisg, yep, gsd-printer shouldn't be running
> (11:43:19 μμ) larsu: cool, set org.gnome.settings-daemon.plugins.print-notifications.active to false

I did that, and after reboot [*] I got a different printer icon and no messages about the "Error: connecting-to-device" (and no notification about the job being completed either).

So the problem that remains is to set that setting to false by default in the gnome-fallback session.

[*] the reboot was necessary because when I tried powering on my printer right after the setting change, I got an apport window about a gnome-settings-daemon crash.

I believe the fix about making org.gnome.settings-daemon.plugins.print-notifications default to "false" may be shipped as a patch of the gnome-settings-daemon package, so I put it in the affects list.
