HP Thinkjet or Quietjet???

You might find a converter like:

Then again, I just looked at the price of some of the converters... the right printer would be cheaper ;-)

If you really must do GPIB, ISA bus cards are cheap. You just need to find an old PC to put them in. I'm surprised there isn't a cheap microcontroller solution though - GPIB is just a slightly more complicated parallel port.

No I need a SERIAL connected printer - the instrument only has a SERIAL interface

AWEM

I think the suggestion was serial into an old PC, and GPIB out, just using the PC as a standards converter (even if a bit bulky!)

FFS if you are going that route. use your main PC equipped with a serial board and drive any damed printer you want any way you can.

I have an old HP Laserjet 4000, that has a serial port on the back, you can get them on eBay or Freecycle if you are lucky like I was!

The object of the exercise is getting a printout from a HP logic analyser which only has a serial port, and a very limited selection of supported printers... So if the only printer it will talk to is only easily available in IEEE-488 then your options are limited a bit.

(although I would be inclined to try a binary capture on the PC and then lobbing the file at a modern PCL printer and seeing what happens)
