Version: (using KDE 4.4.1) OS: Linux Installed from: Archlinux Packages Cups for smb printers have an option AuthInfoRequired. On Gnome, if i print, gnome prompt username/password dialog and print On kde, no dialog and no printing :(
This is a problem with the Qt Print Dialog, so you will need to report it upstream at http://bugreports.qt.nokia.com/secure/Dashboard.jspa
Tracked in https://bugreports.qt-project.org/browse/QTBUG-9135

Everyone, please vote in the Qt bug tracker for this bug! (see comment #2)
The Qt bug report's URL has been changed to https://bugreports.qt.io/browse/QTBUG-9135 P.S. I wonder why the bug is marked as RESOLVED UPSTREAM. Upstream (Qt) has *not* resolved the problem. It should be rather VERIFIED UPSTREAM ...
In the upstream bug, a developer has offered to try and fix this issue. However, he needs access to a printer with authentication. If you might be able to provide this, please have a look at the linked report and comment there.
