Both my host computer and routed computer are using Windows Vista Home Premium.

I've been having many problems trying to share my printer with my new,
routed computer on a wireless network connection. I believe I have correctly
set up printer sharing and my default printer on both computers.

Problem 1:
Today, I find that I'm not able to print from my host computer. When I check
"Printer Status," I'm told that the status can't be displayed with the port
currenlly being used. What should I do to correct this?

Problem 2: (Related to Printer Sharing)
I'm going through the Microsoft document, "File and Printer Sharing in
Windows Vista," again. I found a section, Common Questions with Windows Vista
File and Printer Sharing." I copied and pasted it here. This is related to
Windows Firewall:


"For network discovery of other computers running Windows Vista, you must
allow the following incoming Transmission Control Protocol (TCP) and User
Datagram Protocol (UDP) traffic:

UDP 3702

TCP 5357

TCP 5358"

OK, is this important for my being able to share my printer? If it is, how
do I "allow" "TCP" and "UDP"? The Microsoft document doesn't tell me.

Any help would of course be much appreciated.
