Sensor Select

^JS configures sensor Select. 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.

These are code examples only. This printer or session command does not produce a standalone label image.
