The problem that you're identifying appears identical to my case, which is, that upon OS restart, the system goes through an auto-discovery/auto-install process, and then politely notifies the user via a notification window (the OSD, or on-screen display). Yet then--periodically--this process seems to repeat itself for some as yet unknown reason.
Seems to me that somewhere in the new 17.04 driverless printer driver discovery logic, something is broken. The best I can tell is that the
colord daemon is failing on a missing ICC file for the printer in question, which causes CUPS to want to "reinstall" the printer driver, and hence the repeating "printer installed" OSD message. Perhaps as a clue, when installing a "non-driverless" printer driver, the corresponding ICC is installed correctly.
In my own case, I've solved the problem by preventing CUPS from initiating this auto-everything process entirely. In this way, I install my printer(s) once, and never see a "printer added" OSD messages again.
/etc/cups/cups-browsed.conf, changing the
dnssd line to
Restart CUPS from Terminal
service cups restart
Note that this assumes your printer(s) are on a LAN and not directly connected to your machine. If your printer is local (physically attached), you may want to edit
BrowseProtocols instead (untested).
A restart of the CUPS service or machine reboot should resolve the "printer added" issue. Note that you'll need to manually add your printer(s), as the auto-discovery feature has now been disabled.
