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?
