Nothing shows up about it in the syslog except this, which seems to show up each time the notification comes:
colord[1227]: failed to get session [pid 2331]: No data available -- 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/1725955 Title: "Printer added" notification Status in gnome-settings-daemon package in Ubuntu: Confirmed Bug description: I've recently installed Ubuntu 17.10 (Gnome shell). After a while I saw an OSD notification with the message "printer added", and thought that must be because of the new driverless printers feature in the kernel. I have a brother printer in the network, and I tested it and it worked. The thing is that the message repeats itself, approximately every two minutes, and it's really distracting. I saw a question about this on AskUbuntu (https://askubuntu.com/questions/918462/ubuntu-17-04 -printer-added-notifications-under-gnome), and a solution, but it seemed like no one had filed a bug report.
