Install your shop app
The owner website is only the secure entry point. Install the Windows Auto Print Pilot app on the shop computer; printer discovery, QR generation, pairing, queue handling and physical printing happen inside that app.
Windows app setup
Download and install the app, then sign in inside the app to create the shop QR.
Payment is disabled. Physical printing remains owner approval by default. Automatic printing is unavailable until the printer route and approval service pass their isolated tests.
