Research direction
Start by reproducing the two chained qrimage calls inside device.open and inspect how the printer output differs from the requested layout. Trace the qrimage entry point and determine whether the existing API supports horizontal placement; done means documenting or confirming a supported approach for printing both QR codes on one line.
