I think you mean that there are 2 micro-ribbon connectors; Centronics
used a micro-ribbon connector for their parallel printer interface.
The one labeled "HPIB" is just that, HPIB is HP's implementation of
IEEE-488 (GPIB); the standard cable has stacking connectors on both
ends and is wired straight through (pin 1 -> pin 1, etc.).  The one
labeled 9815 is for a proprietary interface that was only implemented
on HP 9815 computers.  The HPIB interface should work with most GPIB
interfaces; try pretending that it's an HP7475 or other HPGL plotter
(note that HPGL is the language used by HP plotters, and is distinct
from PCL, the language used by LaserJets and other HP printers).

Not an official statement.
