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:
