Here is a table from my Grappler+ manual:

GRAPPLER+ DIP SWITCH SETTINGS
DIP SWITCH POSITIONS                    1   2   3   4
Epson Printers                          *  ON  ON  ON
NEC 8023/C.Itoh 8510                    *  ON  ON  OFF
Anadex Printers/Data South 180          *  ON  OFF OFF
Okidata 82 or 83                        *  OFF ON  ON
Centronics 739-1                        *  ON  OFF ON

* Switch 1 controls the MSB (Most Significant Bit, or 8th
data bit).  When this switch is in the ON (+) position, the
MSB is NOT transmitted to the printer.  When the switch
is in the OFF (-) position, the MSB is transmitted to the
printer and is under software control (se CTRL-I H and
CTRL-I X under TEXT COMMANDS.)
