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 Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1810404 Title: printing options set in control center don't work Status in gnome-control-center package in Ubuntu: Incomplete Bug description: 1. Open settings. 2. Go to Devices / Printers. 3. Click "Add..." and add a network printer with a duplex unit located automatically by the network scan. 4. Click the gear and elect "Printing Options". 5. Change the "Two-sided" option to enable two-sided printing. 6. Close the options dialog and settings window. 7. Print a document with multiple pages to that printer with "lp -d printer-name filename". 8. Observe how it prints single-sided. To get the setting to stick for real, I had to click on "Additional Printer Settings..." and change it there.
