            Bug ID: 456344
           Summary: Driverless printers do not appear in the Qt print
                    dialog
           Product: okular
           Version: 22.04.2
          Platform: Manjaro
                OS: Linux
            Status: REPORTED
          Severity: major
          Priority: NOR
         Component: printing
          Assignee: okular-devel at kde.org
          Reporter: sergio.callegari at gmail.com
  Target Milestone: ---

SUMMARY

The cups spooler offers the possibility to use *driverless* network printers as
long as the `cups-browsed` service is active. With KDE, these printers
correctly appear in the *Printers* section of the *System Settings*.

Unfortunately, while these printers can be used just fine with non Qt
applications, it is impossible to use them in KDE applications like okular,
because they do not get listed in the Qt print dialog, so they cannot be picked
as destinations.

I am observing this problem with Manjaro linux that uses the latest plasma
5.24.5 and framework 5.95.0, together with Qt 5.15.5.

The problem is not there with Ubuntu 22.04, though, that uses the same plasma
and framework versions and a slightly different Qt 5.15.3.

So this issue is to ask to check if wrt driverless printers and the print
dialog:
- something has changed recently preventing the driverless printers from being
shown up in the print dialogs used by Qt applications;
- there is something wrong in the flags used for compiling the code that Ubuntu
may change and Manjaro/Arch tend not to change.
- Qt needs some patches that manjaro is missing.

Note that driverless printing is now becoming indispensable in office
environments where many large printers can only be used via driverless printing
(at least in linux).

I do not think that this bug is the same as #326432 that refers to some very
old problems that should have been resolved long ago.


STEPS TO REPRODUCE
1. Open okular
2. Select Print from the menu

OBSERVED RESULT

Driverless printers are not available in the list of printers. It is impossible
to use them from KDE applications;

EXPECTED RESULT

Driverless printers should be listed in the list of printers and usable.

SOFTWARE/OS VERSIONS
