network printer + DNSSD + External DNS server -> won't print

[Benjamin Flesch]

Binary package hint: cups

My setup:
- Home LAN
- my box: Ubuntu Lucid x64, eth0 is standard interface with DNS set to 8.8.8.8 (Google) and not to our local router
- Samsung ML-2850D (network printer)

Problem:
- Printer is shown active in the printer overview, but doesn't print
- printing jobs fail with "dnssd error", even though everything worked out of the box before upgrading to Lucid

My workaround:

in /etc/cups/printers.conf, replace entry:
     > DeviceURI dnssd://Photosmart%208400%20series%20(D29CFB)._pdl-datastream._tcp.local/
with
     > DeviceURI socket://192.168.178.107:9100

I'm not using a Photosmart printer of course, but the dnssd://-entry looked nearly the comparable.
After I replaced the DeviceURI entry with the socket://-Adress and the local IP Address of my printer, everything worked fine.

My question:
Why did this error occur in the first place - I recall that before upgrading to Lucid, I never read anything about dnssd in cups and underneath my printer the ip address was shown?

During my research I found out about a couple of topics on ubuntu-related forums which addressed the same topic so it seems like a bug and not a mistake on my side.

Is it possible, that the external DNS server is influencing the dnssd in some bogus way?

Thanks for your patience,
