SUMMARY

In `/usr/bin/kcmshell5 kcm_printer_manager`, when I click on "Add printer" and then on "Window printer via SAMBA", the "Browse" button is greyed out.

Instead, by running system-config-printer (the GNOME equivalent), after clicking on Add->Printer, then on "Network printer" and then on "Window Printer via SAMBA", the "Browse" button works and it is clickable (after installing the python-smbc package)

The python-smbc and python3-smbc packages are installed.

Compiling printer_manager from source (https://github.com/KDE/print-manager) does not fix the problem

STEPS TO REPRODUCE
1(a). Run "/usr/bin/kcmshell5 kcm_printer_manager" and click on "Add printer"
or 
1(b). compile it from source and run "kde-add-printer --add-printer"
2. Click on Windows printer via SAMBA

OBSERVED RESULT

"Browse" button is greyed out


EXPECTED RESULT

"Browse" button should work and display the SAMBA tree
