Connection to a Computer
This product has three interfaces that can be used to receive printing data: a
serial port (RS232C), parallel port (IEEE1284, Non-L. P. S.), and a USB port
(USB1.1). An optional internal network interface can be added by your
dealer.
To connect the cable, proceed as follows:
1. Turn OFF both power switches of the printer and the computer.
2. Connect one end of the interface cable to the interface
connector on the back of the printer and secure it with locks or
locking screws, where available.
3. Connect the other end of the interface cable to the interface
connector on the computer and secure it with locks or locking
screws, where available.

Note: If an optional network interface is used, the standard parallel port is
removed from the printer, so the parallel interface cannot be used.
