Connection to a Computer

This product has two interfaces that can be used to receive printing data: a
serial port (RS232C) and a USB port (USB1.1). An optional internal Ethernet,
an IEEE1284 Parallel or Wireless LAN port can be added by your dealer.
With the exception of a wireless LAN connection, an interface cable is
necessary to connect the printer to a computer.
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 the optional Ethernet, an IEEE1284 Parallel or Wireless LAN port is
used, contact your Citizen Systems dealer.
