This started happening to me after I upgraded from Ubuntu 19.04 to 19.10. Now I get a steady spam of pop-ups and the only thing in the logs that seems related are colord messages like the one from #6:

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.
