Variable: ROTATE_DIRECTION
constROTATE_DIRECTION:RotateDirection=90
Direction the Brother QL print head rotates landscape input.
90 = clockwise. Verified once on hardware with a die-cut "F" landscape print (see plan §6 step 1). Identical across every QL model — this is a print-head/leading-edge mechanical fact, not a per-media setting.
