I'm having a similar issue. It says the network printer might be unreachable but eventually mine will print:
3.2.0-24-generic #37-Ubuntu SMP Wed Apr 25 08:43:52 UTC 2012 i686 i686 i386 GNU/Linux
cups ver 1.5.2-9ubuntu1
HP 4100 mfp ( likes to say the printer is unreachable and then within about 10 minutes it will print)
Xerox Docucolor 3535 (driver extracted and loaded from the windows xerox driver - seems to work fine)
