brother-ql / core/src / resolveTapeGeometry
Function: resolveTapeGeometry()
resolveTapeGeometry(
media,engine):TapeGeometry
Resolve per-head-family geometry for a media entry against the engine that's about to print it.
DK entries fall back to the flat printableDots / leftMarginPins / rightMarginPins fields on the entry — the same values every QL code path read before the head-family split landed. TZe and HSe entries dispatch on engine.headDots: 128 picks geometry.narrow, anything else picks geometry.wide. Throws when the requested head family has no entry (e.g. 36 mm TZe on a 128-dot head, or any HSe on PT-P910BT — those engines simply shouldn't reach this call site because findMediaByDimensions gates them upstream).
