It's not parallel, it's HP-IB(HP's version of GP-IB, identical AFAIK). I
never heard of the P model, I though there was just A, B, C and D. No, I
don't remember which one is which. It came in HP-IL, HP-IB, parallel and
serial interface versions. I have the HP-IL version(and a cute litte HP-IL
to HP-IB adaptor), although it is not in use right now(no way to power it
and no drivers for my P-IB card).

Yep, I think so. I'm not sure, since I don't have one of those. A printer
with no power supply... I am told that it uses 8V AC.

It's an HP-IB connector. Cables can be kinda expensive, but I see them at
hamfests sometimes.
>And what do the DIP switches above the parallel interface do?
Sets the HP-IB address.

It IS HP-IB, as mentioned above... So yes.
Of course, I COULD be COMPLETELY wrong on everything I just said...
