said by encom:disabled IGMP and rebooted the router. it seems to have fixed. time will tell if it is permanent. I had rebooted the router in the past and it didn't clear the error so maybe this did it.
thanks!
Had you rebooted the router BEFORE you disabled IGMP (with the problem still presisting) and then you disabled IGMP and reboooted it and the printer worked? Just trying to understand...
