Made the quick check you suggested. Switching off cups, all printers disappear both in okular (QT) and firefox. So it looks like the driverless network printers come from cups.
Weird enough now after the switch off - switch on sequence for cups, I do not have the driverless printers them in firefox either even with cups re-enabled which is weird. This means that there is nothing to disable in the GTK and QT dialogs which seems a good thing. Do you know if some kind of situation where stale files describing network printers could remain around explaining these inconsistent behaviors? If so where? Furthermore, it looks like cups is currently not passing the list of driverless network printers to the print dialog. May it be the case that cups (or the cups dbus notifier) happens to read the cups-browsed configuration file seeking the BrowseRemoteProtocols none configuration option if it is readable? Note that on my system the cups dbus notifier runs as lp and so it cannot read cups-browsed.conf by default since this file is owned by root.root and not readable by others. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1738432 Title: Regression, poor user experience, print dialogs garbled by unidentifiable driverless printers To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1738432/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
