On my system there are more missing or broken options (not only the duplex problem) in the qt print dialog.
On my bionic system i found the following other problems: - the printers are always on color mode, instead of gray-scale. - the option to select the input tray is missing. - the borders can't set smaller then the default. it would be good if not only the duplex option would be fixed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1776173 Title: qt print dialog shipped with bionic ignores printer defaults To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qtbase-opensource-src/+bug/1776173/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
