In order to pave the way for error-free operation of the
Grappler 9 pin, it is recommended that you take each of these
steps one at a time.
STEP 1: Getting to Know Your Software
Some software libraries may hold only one or two pro-
grams, others may include hundreds. Only a few minutes are
needed to divide your library into groups:
Take those software programs that provide support for the
Apple lmageWriter II printer and set them aside. An example
would be Mousepaint for the Apple II, which supports only the
lmageWriter.
NOTE: Virtually all Macintosh and Apple lIGs-specific
applications fall into this category
Make note of any packages which support your particular
parallel printer.
If you are new to computers and have just purchased your
Apple and a parallel printer, the Grappler’s lmageWriter emu-
lation will be the easiest to use. If you wish to use your software’s
printer drivers instead of the Grappler’s, refer to your user’s
guide for printer installation instructions.
STEP 2: Installing the Right Printer
In many cases, a software program must be told what
printer is being used. Even if your software names your printer,
it is recommended that you select lmageWriter or lmageWriter
II, and use the Grappler 9 Pin in emulation mode. This will
eliminate the need to change Grappler switch settings between
applications. Most Mac applications default to lmageWriter
support.
NOTE: If your software takes special advantage of your
printer, you may wish to use its driver and set
the Grappler for Parallel Mode when using that
title, but this will require changes in Grappler
switch settings with each use. If the program is
new and has not been installed, refer to the
program operator’s manual for instructions on
how to install a printer in that program. Do this
before proceeding to the next step.
STEP 3: Setting the GRAPPLER DIP Switch
Once you know your software, you are ready to set the DIP
switch according to one of two modes: lmageWriter Emulation
Mode or Parallel Mode.
If most of your software is set for Apple lmageWriter, as
recommended, then you must use the lmageWriter Emulation
Mode. If your software is installed for your specific parallel
printer, then you would use the Parallel Mode, which renders
the Grappler “transparent” to the code being sent. Again, this
should only be used when your program offers special features
