There is nothing to pair and nothing else to install.
ERPlora runs in the browser and works there for everything except one thing: a browser cannot reach a thermal printer. The app is the same ERPlora, in its own window, with that access — so the till that charges is the till that prints.
The first launch asks which hub is yours and remembers it. From then on the app opens straight into your business.
It scans your local network and asks it by name, so you never type an IP address. If your router later hands the printer a different address, the app follows it.
The app checks what we publish and points you at the new installer. It never interrupts a sale to do it, and it never updates itself behind your back.
