DARKNESS
Description: Set the print darkness to the lowest setting that provides good print quality.
If you set the darkness too high, the label image may not print clearly, barcodes may not
scan correctly, the ribbon may burn through, or the printhead may wear prematurely.
If desired, use the Print Quality Report (FEED self test) to determine the best darkness
setting.
Accepted values: 0.0 to 30.0
