That might be the important point here. If you're going the CUPS+ugen+ hplip way make sure your *printer* is recognized. I don't know how they all play with USB-to-parallel cable.

I don't think there's a USB problem here at least in ugen(4) mode. Maybe your driver needs a firmware and the current ulpt(4) logic doesn't work because you're using an adapter...
