Windows 7: printing to airport extreme from windows 7 pc

Hi all,

Im having a bit of trouble.

Recently i purchased an iMac and an airport extreme base station. I have the wireless set up and it works fine. i can access the internet on any one of my computers. I also have several other computers in my house based on windows 7 and vista.

I want to be able to print off a usb printer that is connected to my airport extreme base station. So far i have only been successful at connecting the iMac to the printer via the base station.

I have followed the directions and downloaded bonjour to connect my windows pc's to the usb printer on my airport extreme. but so far i have been unsuccessful. my windows pcs, say they can see the printer, but when i try to send a test page....nothing happens. its like the test page is just getting lost or blocked.

I really dont know what to do, any help would be great.

Thanks
