haha. ok. I loaded that software and it wants me to select my upstairs printer (as it is the Bonjour Printer Wizard). Perhaps you copied the wrong link? You mentioned the Apple Bonjour Library
Regardless of that, running Emote yields the same results.
I'm pretty sure that link was the right one the last time I used it, which admittedly was quite a while ago. It's a bit misleading that they call it "Print Services" – it actually installs a system component for finding any Bonjour services on the network. Anyway, it sounds like it didn't fix your problem. I don't have a Windows system here at home, so I'll contact a colleague who does.
