Airport Extreme&Express Wireless Printing Help

[Hot Snowboarder]

I have an airport extreme with internet, HDD & printer attached to it. I can print wirelessly from my MBP.

I have a vista machine connected to an airport express via the ethernet port. The express is set up to 'extend a wireless network' and allows the vista machine to access the HDD and internet connected to the extreme.

However, the bonjour printer wizard cannot find the network printer. I think because its trying to find a printer attached to the express (printer is attached to extreme).

Any ideas on how to fix?

I know it's possible for an old eMac hooked up to an AE via ethernet to wirelessly print to a printer connected to the AEBS on the same network because that is the setup I had. (I think I used the WDS option.)
