🖨 SUNMI & iMin • NO IoT BOX

Universal Android POS Printer for Odoo

Print receipts, kitchen tickets and open the cash drawer on Sunmi and iMin Android POS terminals — one module, two native SDKs, zero IoT hardware.

✓ Odoo 19.0 ✓ Sunmi JS SDK ✓ iMin JS SDK ✓ Multi-printer

Universal Android POS Printer turns any Sunmi or iMin Android POS terminal with a built-in thermal printer into a native Odoo POS printer. The module ships both vendor JS SDKs, auto-detects which one to use at runtime, and lets a single POS session drive a receipt printer, a kitchen printer and a bar printer at the same time — no IoT Box, no LAN printer, no ESC/POS hardware.

Supported Android POS Devices

Works on every Sunmi and iMin Android POS terminal that exposes its native Inner Printer service, through the official vendor JS SDKs.

Sunmi V2 / V2 Pro / V2s Sunmi P2 / T2 / T2s / T3 Sunmi D2 / D3 / D2s iMin Swan1 / Swan2 iMin Falcon1 iMin D3 Pro / M2 Max

Core Features

⚡

Native SDK Speed

Sunmi and iMin devices print through their official vendor JS SDKs over an on-device WebSocket. Sub-second latency, full ESC/POS compatibility and cash-drawer support.

🔍

Auto-Detect Mode

The main receipt printer is auto-selected in the order Sunmi SDK → iMin SDK, so most deployments are plug-and-play with no manual driver picking.

🖨

Multi-Printer per POS

Drive several Android printers from a single POS session — a receipt printer, a kitchen printer, a bar printer — each on its own brand and driver.

🍴

Kitchen Ticket Routing

Route order tickets by POS category to any number of kitchen or bar printers, each running its own Sunmi or iMin SDK driver.

📐

58mm & 80mm Paper

Paper width is configured at the POS level and per printer. Layout, margins and font sizing adapt so receipts always stay clean and readable.

🎯

Receipt Customization

Add a logo, a footer message, customer name and a QR code (order reference, website or custom text) without touching any template.

💰

Cash Drawer Support

Opens the cash drawer on cash payments through the Sunmi and iMin SDKs, just like a classic ESC/POS printer — no extra configuration needed.

🔐

Upgrade Safe

Pure extension of pos.config, pos.printer and res.config.settings. No custom models, no core overrides, no monkey-patching.

Two Native SDKs, One Module

Sunmi JS SDK

On-device WebSocket to the Sunmi Inner Printer service. Zero network hops, instant printing on V2, V2 Pro, V2s, P2, T2, T2s, T3, D2, D2s, D3 and every Sunmi model with a built-in printer.

iMin JS SDK

On-device WebSocket plus HTTP bitmap upload to the iMin printer service. Supports Swan1, Swan2, Falcon1, D3 Pro, M2 Max and the rest of the iMin range.

Why Universal Android Print

Save the IoT Box Cost

Skip the Odoo IoT Box, the LAN printer and the extra router per shop. Your Android terminal is both the POS and the printer.

Mixed Sunmi & iMin Fleets

Shops with a mix of Sunmi and iMin terminals no longer need one printer module per brand. One install covers both SDKs.

Works Offline

Printing happens on the device itself via the vendor SDK. Receipts keep coming even when the internet drops.

How It Works

1

Install the module

Install Universal Android POS Printer from the Apps menu. Depends only on point_of_sale.

2

Pick the driver

Set Android Print Mode on the POS config, or leave it on Auto-detect and the best SDK is picked for you.

3

Open the POS

Launch Odoo POS on the Android terminal. Receipts, kitchen tickets and the cash drawer just work.

Universal Android POS Printer for Odoo - Documentation

This module turns any Sunmi or iMin Android POS terminal with a built-in thermal printer into a native Odoo POS receipt printer, without an IoT Box, a LAN printer, or any ESC/POS hardware.

The module ships the two native vendor JS SDKs (Sunmi and iMin) and lets Odoo POS pick the right one per pos.printer record, so one POS session can drive a receipt printer, a kitchen printer and a bar printer at the same time.

Overview

The module ships two print drivers and lets Odoo POS pick the right one per printer record:

  1. Sunmi JS SDK — on-device WebSocket to the Sunmi printer service, using the official Sunmi JavaScript SDK bundled with the module.
  2. iMin JS SDK — on-device WebSocket plus HTTP bitmap upload to the iMin printer service, using the official iMin JavaScript SDK.

Key Features

  1. Works on every Sunmi and iMin Android POS terminal with a built-in thermal printer
  2. Multi-printer per POS — drive a receipt printer, a kitchen printer and a bar printer at the same time, each on its own brand and driver
  3. Auto-detect for the main receipt printer in the order Sunmi SDK → iMin SDK
  4. 58mm and 80mm paper widths, configurable at POS level and per printer
  5. Receipt customization: logo, footer text, customer name and QR code (order reference, website URL or custom text)
  6. Kitchen ticket routing by POS category
  7. Opens the cash drawer on cash payments
  8. No IoT Box, no LAN printer, no extra hardware

Requirements

  • Odoo 19.0 (Community or Enterprise)
  • A Sunmi or iMin Android POS terminal with a built-in thermal printer
  • The Odoo POS is opened directly on the Android terminal in its Chrome / WebView

Note

The Sunmi and iMin JS SDKs only expose their on-device WebSocket to applications running on the terminal itself. Opening the POS from a desktop browser pointing to the same device is not supported.

Installation

  1. Copy the grev_od_universal_android_pos_print folder into your Odoo addons path
  2. Restart the Odoo server
  3. Go to :menuselection:`Apps` and click :guilabel:`Update Apps List`
  4. Search for Universal Android POS Printer for Odoo
  5. Click :guilabel:`Install`

Important

The module depends only on point_of_sale. No additional Python packages or system libraries are required on the server side.

Configuration

Select the print mode

  1. Go to :menuselection:`Point of Sale --> Configuration --> Point of Sale`
  2. Open the POS configuration used on the Android terminal
  3. In the :guilabel:`Printers` section, set :guilabel:`Android Print Mode` to one of:
  4. Select the :guilabel:`Paper Width` (58mm or 80mm) matching the paper roll loaded in the terminal
  5. Click :guilabel:`Save`

Tip

Leave the print mode on :guilabel:`Auto-detect` unless you need to pin a specific driver. Auto-detect is the fastest path to a working POS on mixed fleets.

Kitchen ticket routing

  1. On the POS configuration, enable :guilabel:`Kitchen Ticket Printing`
  2. Pick the :guilabel:`Kitchen Categories` whose products should appear on kitchen tickets
  3. Go to :menuselection:`Point of Sale --> Configuration --> Order Printers`
  4. Create or open a printer record
  5. Set :guilabel:`Printer Type` to :guilabel:`Android Universal Printer`
  6. Choose the per-printer :guilabel:`Android Driver` (:guilabel:`Sunmi JS SDK` or :guilabel:`iMin JS SDK`)
  7. Select the :guilabel:`Paper Width`
  8. Assign the printer to the relevant POS categories

Usage

Reprint a receipt

Reprinting a receipt from the POS order history goes through the same Android driver path, so the behavior is identical to the original print.

Technical Details

Architecture

The module extends three standard Odoo models:

  • pos.config — adds android_print_mode and the full set of per-POS Android printer settings (paper width, receipt customization, auto-print, kitchen routing)
  • pos.printer — adds an android_driver selection and per-printer paper width, used to dispatch each order/kitchen printer to the matching driver
  • res.config.settings — exposes the fields above in the POS settings page

JavaScript drivers live under static/src/app/utils/ and are loaded through the point_of_sale._assets_pos bundle:

  • sunmi_sdk_driver.js — WebSocket ws://localhost:7070/ws, uses the SUNMI global from static/lib/sunmi_sdk.js
  • imin_sdk_driver.js — WebSocket ws://127.0.0.1:8081/websocket plus HTTP http://127.0.0.1:8081/upload for bitmaps, uses the IminPrinter global from static/lib/imin-printer.js

Note

The module defines no new model. All behavior lives on existing Odoo POS entities, which keeps it upgrade-safe and compatible with other POS customizations.

Supported Android POS devices

Brand Example models Driver
Sunmi V2, V2 Pro, V2s, P2, T2, T2s, T3, D2, D2s, D3 Sunmi JS SDK
iMin Swan1, Swan2, Falcon1, D3 Pro, M2 Max iMin JS SDK

Limitations

  • Printing requires the POS to run on the Android terminal itself
  • Only built-in Sunmi and iMin thermal printers are targeted — external USB or network printers are not handled by this module
  • Other Android POS brands (PAX, Urovo, Telpo, Newland, generic OEM) are planned for a future release
