Could you include this patch, please? Description: https://bugs.launchpad.net/ubuntu/+source/system-config-printer/+bug/1232947 Patch: https://launchpadlibrarian.net/155336576/system-config-printer_1.4.2%2B20130920-0ubuntu1_1.4.2%2B20130920-0ubuntu1.1.debdiff Without that fix, the KDE system settings dialog for printers shows the error that scp-dbus-service returned error 1 and you can't add new printers using the KDE dialog. I replaced the brackets manually and it worked. Bug still present in 1.4.3.
