You shouldn't have to use su for system-config-printer, PolicyKit
authorization should just work there, so you should be able to just use it
as a regular user. If it's also broken there, then it's a system-config-
printer bug and will need to be fixed there (and that'd also explain why it
doesn't work in KDE as KDE's printer settings are also based on system-
config-printer).
