I am using a Sony Vaio notebook running Windows XP. I just purchased an Airport Express along with a PowerBook G4 and have my HP DeskJet 5650 connected through the Airport Express. My PowerBook is having no trouble communicating with the printer, but my PC notebook cannot "find" the printer. In talking to Apple Support on this issue, I was told to download Bonjour for Windows, which I did. Once Bonjour was installed, I was still unable to "find" the printer and, additionally, I began receiving an error message stating "The application has failed to start because dnssd.dll was not found." I reinstalled Bonjour to be safe, but the problem continued. Apple Support then suggested I set up an IP print share as an alternative solution, but that ultimately failed to work because my specific HP printer model is not listed. Strangely, and maybe the bigger issue as I attempted to set up the IP print share, when I entered my IP address as 10.0.1.1 which named the port IP_10.0.1.1, it told me the port name was already in use and wouldn't let me continue.
I'm confused and frustrated. Apple Support was as helpful as they could be, but have thrown in the towel and deemed this problem outside the scope of their support.
Can anyone please help?
