HP L 5 manual Bytes are always 1 for this

Example:

?*v6W 00 02 01 01 01 01	# Binary data for CID represented
	in hex. Sets color space to RGB,
	pixel encoding mode to 2. Palette
	size is ignored because this is a
	direct selection, not indexed. Last
	3 bytes are always 1 for this
	mode.
?*r1A	# Start raster.
?*b1V10110000 . . .	# Transfer plane for primary color
	1. Each bit turns on or off the red
	primary for the pixel defined by
	the corresponding bits in each
	plane.

?*b1V01110000 . . .

?*b1W10101000 . . .

#Transfer plane for primary color

2.Each bit turns on or off the green primary of the pixel.

#Transfer plane for primary color

3and move to the next row. Each bit turns on or off the blue primary of the pixel.

MODE 3: DIRECT BY PIXEL

In mode 3, the color raster data is downloaded pixel by pixel (as in mode 1), but each pixel directly specifies each color component (as in mode 2). Assuming Device RGB space with 8 bits per primary, the underlined block below defines the actual color primaries for pixel 1 of row 2.

?*b#W	row 1	r7–r0	g7–g0	b7–b0 . . .
?*b#W	row 2	r7–r0	g7–g0	b7–b0 . . .
?*b#W	row 3	r7–r0	g7–g0	b7–b0 . . .
