I have an Airport Extreme. And I just installed an Airport Express as a usb print server to the existing network. It works great and problem free on my Macbook Pro. I installed Bonjour on my Dell XP laptop. It found the express and the print driver no problem. But the Dell still cannot print. When I set off a print it sits there for a about a minute and then errors out. No particular message just The document failed to print and error -printing under the status. The printer is a Canon MP780, it has the latest drivers and prints fine when connected directly to the Dell. Any ideas?
