Local Network Access
Local Network Access (LNA) is a browser security feature that restricts websites from accessing devices on a local network unless permission is explicitly granted. This enables Odoo Point of Sale to communicate directly with local devices such as ePOS printers without requiring SSL certificates.
Local Network Access allows Odoo POS to securely interact with hardware devices available on the same local network, such as supported printers. Access is controlled by the browser and requires user approval before communication is allowed.
Note
Local Network Access is supported in browsers based on Chromium version 142 or later, including Google Chrome, Brave, Microsoft Edge, Vivaldi, and Opera.
Important
Ensure your ePOS printer is assigned a static IP address. Without this, the device may become unreachable. Static IP configuration should be handled through your router settings.
Activation
To enable LNA in Odoo:
- Enable developer mode
-
Go to Settings ‣ Technical ‣ System Parameters
-
Click New and enter:
-
Key:
point_of_sale.use_lna -

Browser permission
Once LNA is enabled and a local device (e.g., an ePOS printer) is configured, your browser will display a permission request.
Note
-
If the permission popup does not appear, you can manually allow access through your browser’s site settings
-
Some browsers require enabling experimental flags:
-
Brave:
brave://flags/#local-network-access-check -
Chrome:
chrome://flags/#local-network-access-check
-
Check LNA status in POS
To view the current LNA status:
- Open the POS register
-
Click the menu icon (☰) in the top-right corner
-
Select Local Network Access
A popup will display the LNA Permission status, showing whether access is granted or blocked.
