labelwriter / core/src / encode550Label

Function: encode550Label()

encode550Label(device, bitmap, options?, media?): Uint8Array

Encode a complete 550-protocol print job for one or more copies.

The bitmap is fitted to the engine's headDots (right-padded if narrower, cropped if wider) so each raster line is exactly headDots / 8 bytes. Copies share the same bitmap; each gets its own ESC n index and ESC D header. Inter-copy feed is ESC G; the final feed is ESC E. Job is closed with ESC Q.

compress is silently ignored — the 550 raster format does not carry the 450's SYN / ETB framing and therefore cannot RLE.
