Receipt printers

Supported printers

Important

Epson printers are highly recommended for use with Odoo.

The following printer types are supported:

• Network printers (ePOS protocol)
  Work without IoT (e.g., Epson TM-m30 iii models 112 or 152)

• ePOS USB printers
  Require connection through an IoT system

• ESC/POS printers
  Must be connected via an IoT system (USB or network)

Note

Bluetooth printers are not supported by Odoo.

Configuration

To set up a receipt printer:

1. Connect the printer to a power source

2. Connect it to the network (Wi-Fi or Ethernet)

3. Turn it on

The printer will automatically print a ticket displaying its IP address. Keep this information for setup.

Connect printer to POS

1. Go to Point of Sale ‣ Configuration ‣ Settings

2. Scroll to Connected Devices

3. Enable ePos Printers

4. Enter the printer’s IP address

5. Click Save

Enable secure communication

To allow POS to communicate with the printer:

• Enable Local Network Access (LNA)

or

• Configure a self-signed certificate

Directly supported ePOS printers

The following models are fully tested and recommended:

• Epson TM-m30 i / ii / iii (Wi-Fi or Ethernet)

Other Epson printers supporting the ePOS protocol may also work.

Important

• The printer must support HTTP mode

• When using LNA, the printer must have a static IP address

Printers requiring IoT

The following models require an IoT system:

• Epson TM-T20 series

• Epson TM-T88 series

• Epson TM-U220 series

Troubleshooting

If issues occur, check the following:

• Indicator lights: Use blinking patterns to diagnose problems

• No IP ticket printed: Verify network connection (Wi-Fi or cable)

• Blank receipt: Check paper roll orientation

• Connection failure:

  • Confirm the IP address in Odoo matches the printer

  • Ensure the printer has a static IP assigned

This ensures reliable communication between Odoo POS and your receipt printer.
