Internet Printing Help

I am trying to figure out how to setup, of if I can setup,
Internet printing in Win XP Pro. I setup the Internet
connection, and I am even able to pull up my printers from
a web browser, but I alway get an error when I try
to "connect"

Is there a special TCP port I have to release in my
Firewall? (Although, I tried with the firewall off)

On my last attempt, I get this error after is paused on
verifing login name (even though I didn't have to tell it
my user name and password)....


Printer Installation Failed

The handle is invalid.


Thanks,
Mike
