Installation and Quick Setup 
Next, press and hold the SETUP button. After approximately one second, the display will 
show “Setup: FORMS” and beep once. Continue to hold the SETUP button for 
approximately one more second until the display shows “Setup: INTERFACE” and beeps 
twice. Then release the button. You have now entered the printer's interface setup menu and 
can now proceed with the instructions listed below for the interface you desire to use. 
Parallel Interface 
The 36-pin connector for the parallel interface is located on the rear of the printer 
immediately above the power cord connector.  Connect a shielded cable between your 
computer and this connector. The pin-out for this connecter is shown in the following 
diagram.

signal which indicates a 
paper out or paper 
jammed condition. 
A printer generated 
signal which indicates 
that the printer is on line 
and ready to receive data. 
Signal ground.
