Please see attached animated GIF. Open gnome-control-center, it says printer is there, try to delete it, it says it was deleted but error in terminal says it wasn't because it doesn't actually exist, close gnome- control-center, re-open it, printer is back, close it again.

The printer in question IS NOT LISTED IN /ETC/CUPS/PRINTERS.CONF. I honestly have no idea where gnome-control-center is getting it from. I had a theory that maybe a previous invocation of gnome-control-center removed it from printers.conf but didn't tell CUPS to reload, so it was in memory in cupsd but not on disk, but I tried restarting cupsd and the problem persists. I literally have no idea where gnome-control-center is getting that printer from. Please don't ask me for any more information, I'm sick and tired of this and I've already wasted too much time on it. All the issues I've reported have been extremely easy for me to reproduce. If you are unable to reproduce them, I have no idea why and have no time to help you further. If you haven't even tried, then stop wasting my time. ** Attachment added: "animated gif of problem" https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1810404/+attachment/5228311/+files/Peek%202019-01-10%2009-00.gif -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1810404 Title: printing options set in control center don't work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1810404/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
