In Ubuntu 14.10 (Utopic), there are two packages that can be involved in gnome printer norifications: gnome-settings-daemon and unity-settings- daemon. The latter package seems to be a fork of the former, for Unity use I suppose.
These two packages come with a printer notification plugin. The one of gnome-settings-daemon is /usr/lib/gnome-settings-daemon/gsd-printer and the other is /usr/lib/unity-settings-daemon/usd-printer. I found that if the gnome-flashback session (a.ka. "Gnome Classic") is used, the printer notification plugin involved is usd-printer, from the unity-settings-daemon package. I guess that gsd-printer is used in a Gnome Shell session (I don't use it so I can test my guessing). So, to remove the connecting-to-printer false error message, I think the safest approach is to patch both packages, just by adding the lines: if (g_str_has_prefix (reason, "connecting-to-device")) return TRUE; to the reason_is_blacklisted() static function in gsd-print- notifications-manager.c. A patch is attached for the gnome-settings-daemon package and I'll also fill a bug report with a patch for the unity-settings-daemon package. ** Patch added: "suppress-printer-connecting-to-device-notifification.patch" https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/1202198/+attachment/4329475/+files/suppress-printer-connecting-to-device-notifification.patch -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1202198 Title: gnome-settings daemon notifies as error an info message Status in gnome-settings-daemon package in Ubuntu: Confirmed Bug description: When sending a document to a printer, gnome-settings daemon will show a message like: ERROR: connecting to printer Nevertheless, the document will print without any issue. Actually this message is a warning or info message, as it is telling the user that it is connecting to the printer. This leads to users sending twice or more any document as they think an issue has happened.
