2. Parallel Mode. If your software application allows
for selection of a specific parallel printer (not the
lmageWriter), verify that switch handles B, C and D
are set in the ON position. If you are printing
graphics (8 bits), the A handle should also be set in
the ON position.
The DIP switchs are a rocker type switch. In order to set it
properly, push down on the ON side to set it ON and push down
the OFF side to set it OFF. Always unplug the Grappler 9 Pin
power supply while changing the DIP switches.
The following illustration shows a setting of ON-ON-OFF-
ON.
NOTE: Whenever a DIP switch setting is changed, the
power supply must be unplugged from the
Grappler for 5 seconds, and then reconnected.
This allows the Grappler to “see” the change. If
using a Macintosh you must also restart your
computer.
Important Note:
Whenever you print text-only on an Apple II in the
parallel mode, switch handle A should be set to the off
position.
After the GRAPPLER DIP switch has been se to
match your printing application, test the work you have
done.
