BRIEF
A retail team wanted to test their POS flow without shipping printers to every dev's desk.

How it works
The app runs on Android. It listens for the same ESC/POS command stream the real Epson TM-m30II accepts, parses it, and renders the receipt to a preview on screen. From the POS application's side, it looks and responds like the physical printer.
