HP L 5 manual Byte 2 Number of Bits per Index, Byte 3 Number of Bits for Primary #1

Example:

?*v6W	00 03 00 08 08 08	# Binary data for CID
		represented in hex. Sets color
		space to RGB, pixel encoding
		mode to 3. Palette size is
		ignored. Send 8 bits to address
		each primary value for a pixel.
?*r1A		# Start raster.
?*b3W	45 06 30	# Each byte sets a primary
		value for the first pixel and
		moves to the next row (45

specifies the red, 06 the green, and 30 the blue component value of that pixel).

Byte 2 (Number of Bits per Index)

In all pixel encoding modes, this byte sets the size of the palette to 2n, where n is the number of bits per index.

•In pixel encoding modes 0 and 1 (indexed), where raster data is interpreted as indices into a palette, this value specifies the number of bits required to access all palette entries.

•In pixel encoding modes 2 and 3 (direct), this value determines palette size, but has no effect on the specification of raster data.

Byte 3 (Number of Bits for Primary #1)

This byte is ignored in pixel encoding modes 0 and 1, but affects the black and white references in device-dependent color spaces. In Device RGB, the black reference for primary #1 is set to 0 and the white reference is set to 2n – 1, where n is the number of bits for primary #1. These references are reversed in Device CMY color space.

•In pixel encoding mode 2, this byte is ignored except in Device RGB and Device CMY color space, where it designates the number of data bits needed to specify primary #1, as well as the number of data planes to be sent for primary #1.

•In pixel encoding mode 3, this byte designates the number of data bits needed to specify primary #1.
