Troubleshooting

1. Connectivity

• Odoo shows “Your print service is offline”
  • Check that the client-side app is installed and running (look for the tray/menu bar icon).
  • Refresh your Odoo browser tab to trigger reconnection.
  • Click the printer icon in the Odoo top-right tray to manually reconnect. The icon turns blue when connected.
  • Ensure your firewall/security software allows traffic on port 32276.
  • Windows Store build: if persistent connection/settings issues occur, uninstall the Microsoft Store version and install the .msi from the Omni Print website.

• Cannot connect in Apple Safari
  • Cause: Safari enforces stricter local service access policies.
  • Solution: Use Chrome or Firefox to access Odoo.

2. Print quality and formatting

• POS receipt logo or images look squashed
  • Fixed in client-side app v1.2.2+. Please update to the latest version.

• Kitchen printer content is cut off
  • Increase Feed Lines in the client-side app under the POS tab to ensure enough space before cutting.

3. License and activation

• macOS asks for the License Key after every restart
  • Please update to latest version to avoid this issue.
