Interface: BrotherQLMedia ​

Brother QL media descriptor.

Extends MediaDescriptor with the dots-based geometry the raster encoder needs. The base palette field flips the driver into multi-plane mode — only DK-22251 declares one in the registry.

Properties ​

dieCutMaskedAreaDots? ​

optional dieCutMaskedAreaDots?: number

Die-cut page length in dots at 300 dpi: the reference's "print area length" (§2.3.2(b) column 4). The encoder sends exactly this many rows for die-cut media; see DECISIONS D20.

geometry? ​

optional geometry?: object

Per-head-family geometry. narrow = 128-pin head (PT-E550W, PT-P750W); wide = 560-pin head (PT-P900 family). DK entries leave both unset and use the flat fields below; TZe / HSe entries leave the flat fields undefined and populate narrow and/or wide per the Raster Command Reference PDFs. undefined on a head family means "this tape doesn't fit this head" (e.g. 36 mm TZe and 31 mm HSe-3:1 have no narrow entry).

narrow? ​

optional narrow?: TapeGeometry

wide? ​

optional wide?: TapeGeometry

id ​

id: number

Unique identifier within the driver family.

Overrides ​

MediaDescriptor.id

leftMarginPins? ​

optional leftMarginPins?: number

printableDots? ​

optional printableDots?: number

DK-only flat geometry. PT-* entries populate geometry instead.

rightMarginPins? ​

optional rightMarginPins?: number

tapeSystem ​

tapeSystem: TapeSystem

Tape system this entry belongs to. Drives lookup gating in findMediaByDimensions(width, height, engine) so QL engines never resolve TZe / HSe entries and vice versa.

type ​

type: MediaType

Media type classification — driver-specific string values.

Common values: 'continuous', 'die-cut', 'tape'. Drivers may define additional values as needed.
