Connecting The Printer To The Host Pc / Pos Terminal - Epson TM-U330 Technical Reference Manual

3.3.4 Connecting the Printer to the Host PC / POS Terminal

All cables are connected to the connector panel located on the lower rear side of the printer.
Note:
The figure above shows the connector panel for the serial interface model printer. The shape of the interface
connector varies according to the type of interface used.
Be sure to turn off the power supply for both the printer and the host computer unit before connecting the various
cables.
You need an appropriate serial, parallel, USB, or Ethernet interface cable to connect your computer to the printer.
For the serial model, it is important that you use a null modem cable, not any other serial cable, and for the
parallel model use an IEEE 1284 cable.
3.3.4.1 Serial Interface
Before connecting any of the cables, make sure that both the printer and the host PC are turned off.
1. Plug the cable connector securely into the printer's interface connector.
2. If the cable connector has screws on it, tighten the screws on both sides of the connector.
3. If your interface connector has a grounding wire, attach it to the printer using the screw labeled FG,
which is next to the interface connector.
4. Attach the other end of the cable to the host PC.
