I'm setting up my Dad's laptop (Vista) to print to an HP Deskjet printer attached to a Windows XP Desktop box. The XP box is running Windows firewall.

Laptop sits on 192.168.1.66, Desktop 192.168.1.65.

I set up logging in the firewall, and determined that it is dropping inbound packets on TCP port 9100, used by JetDirect, the printing protocol.

I set up an exception on TCP port 9100, allowing access to the local subnet. There's also an entry under the 'allow applications' tab which was marked for the exact printer model. I selected this as well, then tried to print again... I see more dropped packets from 192.168.1.66 to 192.168.1.65 for TCP port 9100.

What do I try next?
