I've got an HP thinkjet printer here, model 2225P.
It's a
battery-operated unit with a parallel interface.
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).
The battery pack has a 2-pin plug on the back, which
looks as though it
connects to the standard HP 8V 3W charger. Is that right? I've got those
by the dozen...
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.
The parallel interface is a DA15-S connector. Does
anyone know the
pinout. I'm pretty sure (from looking inside) that it's TTL level and a
subset of a centronics port.
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.
I've got the user manual for the GPIB version - are
the escape sequences
the same?
It IS HP-IB, as mentioned above... So yes.
Of course, I COULD be COMPLETELY wrong on everything I just said...
