Interface Connection
The G-2108/G-3106 supports RS-232 Serial, USB Device, Ethernet and Centronics parallel connections.
Centronics parallel connection requires an optional Centronics parallel Interface Card.
Note: When connecting the G-2108/G-3106 printer to a computer via the USB interface cable, make sure to utilize
the same USB port used during the driver installation process, which enables the printer to retrieve needed
commands or data from the PC. If the same USB port is not available or not known, then in the printer’s Properties
Dialogue Box, under the Ports tab, ensure the current port location is checked.
To connect:
1. Make sure the printer is powered OFF.
2. The printer will identify the communication port automatically.
3. The default values of printer port can be obtained from the self-test report. (See Chapter 2: Operation Basics/
Advanced Functions/ Self Test)

guide.
5. Please take the following measures to reduce cable noise.
- Restrict the length of the interface cable to less than 6’ (1.83 M) if possible.
- Keep the interface cable separate from power cords.
