Connect your web apps with printers and local hardware

EasyHardware Bridge is a small service installed on the computer that lets any web application print without dialogs and read from or write to serial ports (scales, scanners, POS…) directly from the browser.

It works with any web application, with or without Dolibarr. It is also the engine behind our EasyHwConnector module for Dolibarr, and is sold separately.

What it solves

Zero-click printing from the browser: ESC-POS, PDF and PNG/JPG receipts, with reusable templates.
Scales and serial peripherals: real-time weight reading, barcode scanners, PIN pads and bidirectional communication.
Multi-printer and multi-port mapped by key: your web app does not need to know the device's real name.
Dependency-free JavaScript SDK served by the bridge itself, plus an HTTP API to integrate it with any backend.

Ideal for

Web POS: silent receipt printing.
Web warehouse / WMS: live scale weight and delivery-note printing.
Any web application that needs the user's local hardware.

Robust and production-ready

Persistent print queue with retries, backup and startup on boot (kiosk/headless mode).
Web panel protected with username and password, Prometheus metrics and live logging.
Cloudflare tunnel integration to publish it without opening ports.
Runs on Windows, macOS and Linux, with any modern browser.

Per-activation license, valid offline. Contact us for your serial or a trial.
