What you’ll learn
Modern browsers don’t trust local devices. If your app runs over HTTPS, printers, scanners, and even USB devices with no network interface are blocked unless they can be accessed securely - and new Local Network Access restrictions are making this worse. In this talk, I’ll walk through what’s happening under the hood, show a real-world workaround using Electron, and break down what actually works (and what doesn’t) when connecting web apps to local hardware.
