^MD — Media Darkness

Print ControlSupported

Plain English

Adjusts how dark the print is — like the darkness/contrast setting on a printer. Higher values mean more heat, making darker prints but using more ribbon and potentially reducing printhead life.

When to use

When barcodes aren't scanning well (increase darkness) or when print is smudging/bleeding (decrease darkness).
