Set RF Power Levels for Read and Write

^RW configures set RF Power Levels for Read and Write. It applies to the printer session and subsequent formats and controls printer hardware or connectivity rather than label pixels.

ZPLr compatibility note

  • Recognized by the renderer but has no label-raster effect.
