They are mostly for affecting the screen dumps from BASIC. I found
this on Ground (I cut off the end, which was about AE's Phasor sound
card):

Sure.. :)

I have two standard Grappler+ cards, as well the the 64k Buffered
Grappler+ version. The DIP switches are used to configure your card
for a series
of different printers out there (I'll list those settings below). You
may also
want to test the RAM memory on your Buffered Grappler+, so do the
following
to invoke it's built-in self test. Making sure the card is installed
in slot
#1, with the cable attached to the printer and the printer online with
paper
in it, turn on your Apple II with the RESET key hold down, then
release it
after 2-3 seconds. If you've done this correctly, a message will be
printed
saying the test is in progress. After 45 seconds the status of your
RAM chips
will be printed, numbered 1 to 8. If an "X" appears, this indicates
the absence
of a RAM chip or a _bad_ chip. If you see a "1", this means a DRAM
chip has been
found at the location and tests good. The cable you need is very
common, and
all my other Apple II printer cards use it. It's a 26-pin female, to a
25-pin
centronics ribbon cable.
