Parallel Connection: The parallel interface supports directional communications. Choose and 
connect your cabling as follows: 
•  For unidirectional communication, use a Centronics IEEE 1284 cable with a 36-pin male 
connector.  
•  For bidirectional communication, use an IEEE 1284 Compliant cable with a 36-pin male 
connector (and supporting host software). 
 
 
 
 
Serial Connection: The serial interface supports RS-232C, RS-422, and RS-485 
communications via a DB-9 connector (click here for details). Serial interface cabling must 
make specific connections (pin-outs) for proper data exchange between the host and printer 
(see note below). The different pin-outs and part numbers are shown below (contact your 
reseller for ordering information).  
 
 
 
In addition to the hardware configuration, the serial port settings must match the host 
computer's serial port settings. Refer to the Communications branch of the menu to make 
these settings. Basic connections are shown:
