That makes absolutely no sense to me. If you cannot using DNS-SD for some reason, you can still use the "CUPS > Browsing" protocol as used by CUPS < 1.6.

Or is it per application only? If it's per-application I'm guessing I'll have to do the latter because cups-browsed doesn't appear to be available on F18... # repoquery --whatprovides /usr/lib/systemd/system/cups-browsed.service (no results) Thanks, Richard
