I had the same problem with my Model 217, but only if I had a disc drive on
the same HP-IB as the printer (and only when the printer was a "simple"
HP-IB printer, rather than one using AMIGO pacing protocol, such as a 2631B).

This was a bug in that version of HP-UX.  It was corrected in revision 5.1
(which was the next revision after 2.3).

It would be fairly expensive to fix, since an upgrade to 5.1 on the Model
236 requires swapping out your MC68000 CPU board for an MC68010 board, in
addition to acquiring the software itself.  If you have a spare I/O slot, it
might be cheaper to add a second HP-IB card (98624A).

If you have a serial port available (98626A, 98628A or 98644A card), it
might be less costly to replace the 2671G with a generic serial printer.
