The printer‘s RS-232C parameters are factory-set to
the following values:
Baud rate=9600 bps, data bits (character length)=8
bits, stop bits=1, parity=none
The two RS-232C protocols are XON/XOFF and
DTR. The printer performs both of them
simultaneously, using positive logic for DTR.
If you are uncertain as to the printer’s current
parameter settings, you can reset them to the values
listed above.
Set the computer to the same parameters as the
printer. On many computers this can be done by set-
ting DIP switches before the power is turned on. An-
other method is as follows:
