Picture of the notification
An OSD notification with the message "printer added" pops up approximately every two minutes. I'm in a network with a network printer, and it's that one that pops up.
This message gets printed to the syslog each time the notification pops up:
colord: failed to get session [pid 2331]: No data available
I haven't installed any special printer/scanner drivers at all.
Operating system: Ubuntu 17.10, GNOME Shell 3.26.1 (the default included one)

I have a theory that this is related to the network. Specifically when a DHCP lease is renewed (most common scenario) or when the wifi drops out and back in again.
Looking at my syslog, I think I can corelate DHCP renews with the message popping up.
When I join a network with dozens of printers the notifications just don't stop. The existing gsettings key org.gnome.settings-daemon.plugins.print-notifications doesn't prevent them from showing up.
