Comment 15 for bug 959195

Six years later, this is still a problem in Ubuntu 16.04.3:

$ ps -ef | grep cups
root 478 1 0 14:31 ? 00:00:00 /usr/sbin/cupsd -l
lp 584 478 0 14:31 ? 00:00:00 /usr/lib/cups/notifier/dbus dbus://

I followed the suggestion in comment #4 and it got rid of the notifier processes BUT in a short time (a day or two) they came back, about one or two processes a day. So, the fix does not appear to be working.

Note that this is not just plain "indicator-printers" setup --- I am running HP notifier "hp-systray" which is part HPLIP (without it my printer wouldn't work as it is a "windows only" printer LaserJet Pro M102a).
