The phrase 'you lucky beggasr' springs to mind

It's the same printer as is used with the HP48S/SX/G/GX, the
HP41 (with 
the IR module), etc. It's a lot easier to find that the
LogicDart. I 
picked one up from a frined at HPCC along with a lot of
other old HP stuff...

Be warend that the IR transmission to the printer is one-way
only (no 
handshake, even) and is none-too-reliable. I find that
perhaps one dump 
in 5 is mangled and has to be done again. You also have to
position the 
LogicDart and printer just right (not easy when you've got
the former 
balanced on top of a PDP11). The thermal printing doesn't
last that long 
either (it fases with time), but that's easy to get round by
photocopying 
(or I guess scanning) the printouts.
