If it's a stock Dapper install the following lines should already appear
in /etc/cups/cupsd.conf:

<Location />
  Order allow,deny
  Allow localhost
  Allow @LOCAL
</Location>

This last Allow line grant access from all interfaces. Port 631 is
already open since we added the following lines to
/etc/cups/cups.d/ports.conf:

Listen *:631
Listen /var/run/cups/cups.sock

Those two sets of directives are generally what allows cups to listen
and accept jobs from the network (in this case with virtually no
restrictions).

You certainly can check to make sure cups is listening by using:

$ netstat -l -t | grep ipp

Which should return something like:

tcp        0      0 *:ipp                   *:*                     LISTEN
tcp6       0      0 *:ipp                   *:*                     LISTEN

My questions for Norman at this point would be...

   1. Have you verified network connectivity between the windows box and
      the ubuntu box? Can you ping servername or ping ipaddress?
   2. What happens when you open a browser on the windows machine and
      browse to:
      http://ipaddressofcupsserver:631/printers (you should see a web
      page that shows your printers).
   3. What is the name of your printer as recognized by cups?
   4. When you make the connection using the windows Add Printer wizard,
      are you using hostname or ip address? If you are using hostname,
      are you sure this is resolving correctly?
   5. What does /var/log/cups/access_log or /var/log/cups/error_log say?

I've helped lots of people help set up windows -> ubuntu printing this
way. Unless you have made some other changes to the cups configuration,
or have a connectivity issue between the 2 machines, we should be able
to get this done.

... and this is still far easier than getting samba configured! :)
