An HP ThinkJet, model number HP 2225A, are on the used equipment market for $100 to $200 range and ink cartridges are still available for $15 to $25.
I had one and used it extensively when trying to figure out home some one else's program worked (programmer and source long gone). Very useful way to bug a program and find out what is really going on. Also a lot cheaper then a true GPIB analyzer.

Or considering that you have a 9826, do you also have an HPIB Printer? If
so, many of them could be set to a "Print All" mode (some setting of the
address switches). It will then print all the bus traffic. I use to use
that as a bus monitor when I couldn't get a "real" one. (And the fact that
it printed was better than the real one - since I was interrested in command
sequences, not timing that the real bus monitor gives.)
