I seem to remember there was a converter (sold by Black Box, IIRC), but
the chances of finding one is pretty slim. You'd be more likely to find
a printer. Building your own converter would be the easiest as Ethan
suggests.
If you can find the manual on the DMB32 it should have the pinouts for
the cable, which will make building a converter even easier.
