While Gutenprint is able to generate printjobs that are expected to work 
with the UP-DR80MD, the details on how to actually communicate with the 
printer are unknown.

I'd hoped that the printer, in virtue of supposedly accepting standard 
HP-PJL, would not require special handshaking between gutenprint and the 
printer, but alas, you've confirmed more work is necessary.

What's needed at this point are USB sniffs between Windows and the 
printer, so that the appropriate communication code be written.

Installing Wireshark, and saying yes to the optional usbpcap 
installation, will provide all necessary software; then you'll need to 
start a capture and fire off a couple of prints (the standard windows 
test print will suffice).

Once I get the sniffs, I should be able to make rapid progress, but 
there's going to be at least a few rounds of back-and-forth testing.
