The 25-pin D-type connector with pins (DB25P=male for the A1000, female
for A500/A2000 and IBM compatibles) at the rear of the Amiga is nominally
used to interface to parallel printers.  In this capacity, data flows from
the Amiga to the printer.  This interface may also be used for input or
bidirectional data transfers.  The implementation is similar to
Centronics, but the pin assignment and drive characteristics vary
significantly from that specification (see Pin Assignment).  Signal names
correspond to those used in the other places in this appendix, when
possible.
