media.media_low.external

This printer setting gets the status of the external
media.media_low
 warning.

Getvar

To instruct the printer to respond with the currently set media print mode:
! U1 getvar "media.media_low.external"
Values
  • "0"
     indicates paper present at sensor position
  • "1"
     indicates no paper present
The status of the sensor is sampled every time the printout is cut. If three succeeding samples show "no paper", the status reply changes to 1. This is to prevent a false alarm if the side of the paper roll is not clean. If the current status of the sensor is required, use
~HQES
 and extract the paper near-end sensor bit.
