Signal Voltage and Current levels
The serial interface meets EIA RS232 interface specifications:
Voltage Levels
Mark = Off =
Space = On =
Because both the host and printer are DTE's (Data Terminal Equipment), they use the
same serial port pin-outs. If the cable that is used to connect the host to the printer is a
pin-to-pin inter-connect, it will not work. Therefore, a null modem or turn-around cable
must be used to interconnect the host and the printer.
Display Pass Through
The display pass through feature allows a pole display to be interconnected with the
printer. The printer is connected to a host system with a special serial cable. The host
sends serial data to the printer and the printer sends serial data to the pole display. The
printer does not provide power to the display. During normal printer operation, no data is
passed to the display. In pass through mode, all received data is passed on to the
display.

USB Interface

The USB interface is a Version 1.1 interface that is Version 2.0 compliant. The standard
USB interface card is implemented through a Standard Series "B" Receptacle as defined
in the USB Specification. The printer is self-powered and does not draw power from the
standard type B USB interface cable.
The Standard USB Type B connector has the following pin functions:
