I have recently tried to use a HP LaserJet IIP with a HP
Postscript cartridge, but without Appletalk. I want to use
the serial port (printer port) on my mac. I have managed to
find a copy of the instructions on how to modify the standard
Apple LaserWriter driver to use the serial port, but this
set up didn't work for me. I would get PS ERROR 18 on the
printer. I think there is simply something wrong with my
cable which I made myself. I only used 5 pins of the Din-8
and RS-232 connectors. Unfortunately I can't get the Din-8
connector appart and can't remember the pins I used, but I
do have the pins of the RS-232 that I used. They are pins
2 (TD), 3 (RD), 6 (DSR), 7 (GND), and 20 (DTR).
So the questions are:
1. What is the correct pin connections for a serial cable
from the mac printer port to the serial port of the
HP LaserJet IIP?
2. Has anyone successfully used a HP LaserLet IIP with a
postscript cartridge, but without the AppleTalk Card?
Any help is GREATLY appreciated!! Thanks!
