The 2225B was the original battery powered unit (runs
off 6 sub-C NiCd
cells in a special HP battery pack [1]). It was designed to be used with
portable computers and calculators (HP41, HP71, HP75, HP110). The only
problem is that there is no way to fix a paper supply to it. Presumably
you're supposed to take a stack of fanfold paper, the printer, the
printer stand, and the HPIL cables around with you. Then find a desk to
set the stand and printer on, feed in the paper and print something.
Printer stands to go with Thinkjets? Luxury! Where I worked at the
time we didn't buy them, not even for the HP-IB ones that pretty much
stayed where they were. Most folks either stacked the paper somewhere
behind the printer and dealt with the resulting loss of desk space
and/or mess of tangled supply paper, printer paper, and cables; or
kludged a stand out of an empty cardboard box.
Quite honestly I've never had to print anything in
a location where
there's a desk but no mains supply. But anyway...
It saved you having to fuss with the wall wart until you ran the
battery down. But you're right, we had a couple HP-IL Thinkjets to go
with a couple 110s and people who used the 110s mostly didn't bother
with the Thinkjets -- they were either using the 110 to dial up the
3000 from home and didn't need a printout, or they were doing some
work at home that they would bring back the next day and could print
on an HP150.
