D — Heat density

Print head heat/darkness setting. Being a device setting it does not change preview output; on a real printer it sets darkness.

Engine status: Parsed, not rendered

The engine recognises the command and skips it: it is a DEVICE setting and does not change the image on the media. Your label still parses cleanly.
