This all depends on where the firewall is. If you are relying on the
firewall on your router, and the machines you want to connect to are on
the local network side, this isn't an issue. However, if you are running
a firewall on your ubuntu machine, then port 631 could very well be
blocked, and that would explain why you cant make a connection.

Based on your previous posts, it appears port 631 is listening on all
interfaces. The question here is what is stopping your windows machine
from connecting to port 631. What happens if you open a command prompt
on your windows machine and type (where ubuntu_server is the host name
or ip address):

C:\> telnet ubuntu_server 631

Do you get a "Could not open connection to the host" error?

One other thought, are you in fact specifying the port when testing the
connection via your browser? In other words, typing the following
address with 631 specified in the address in your windows browser (where
ubuntu_server is the host name or ip address):
