For me it all seems like GNOME (and its underlying GUI library GTK) is not able to fully access the printing system, but other applications, desktops, and GUI libraries are able to fully access.
Could you set CUPS to debug logging: cupsctl --debug-logging and do 2 tests: 1. Open the print dialog of evince 2. Open the "Printers" page of the GNOME Control Center After each test copy the file /var/log/cups/error_log and attach the copy to this bug report. Do not compress the files and do not package them together. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/2083530 Title: gnome-control-center not able to add printer or make settings Status in cups package in Ubuntu: Incomplete Status in gnome-control-center package in Ubuntu: Incomplete Bug description: don't know why, but i'm no more able to add a printer or make specific settings and also unable to remove it.
