Resolution / Answer

The ~RO command resets the advanced counters used by the printer to monitor label generation in inches, centimeters, and number of labels.


The 'RFID VALID' and 'RFID VOID' counters can be seen on the configuration label and depending on which printer is being used, on the printer's LCD as well.
