USB devices get attached to a driver that handles the class preferentially. ulpt is one of these, for printers. ugen is basically a generic driver that just supports user-space commands. Typically one uses libusb for this. Some of the newer printers seem to have only support in hplip via libusb/ugen(4) and not ulpt(4). To debug this, you are likely going to have to turn on debug logging in various places and pore over the logs to see what is going on. And also I suggest learning how to use ktrace.
