# Receipt printers

Receipt printers can be connected to Odoo Point of Sale to automatically print receipts for completed transactions once properly configured.

## **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 <a href="https://www.odoo.com/documentation/19.0/applications/general/iot/connect.html" target="_blank" rel="noopener noreferrer">**IoT system**</a>

- **ESC/POS printers**\
  Must be connected via an <a href="https://www.odoo.com/documentation/19.0/applications/general/iot/connect.html" target="_blank" rel="noopener noreferrer">**IoT system**</a> (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 <a href="https://www.odoo.com/documentation/19.0/applications/sales/point_of_sale/hardware_network/pos_lna.html" target="_blank" rel="noopener noreferrer">**Local Network Access (LNA)**</a>

**or**

- Configure a <a href="https://www.odoo.com/documentation/19.0/applications/sales/point_of_sale/hardware_network/epos_ssc.html#pos-epos-ssc-certificate" target="_blank" rel="noopener noreferrer">**self-signed certificate**</a>

**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 <a href="https://www.odoo.com/documentation/19.0/applications/sales/point_of_sale/hardware_network/pos_lna.html" target="_blank" rel="noopener noreferrer">**LNA**</a>, 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.
