Command / Parameters		Function / Result
ESC*b#M		Set Raster Compression Mode
0	Uncoded (Default)	Identifies the compression mode the host uses to transfer RIG data.
1	Run-Length Encoded	For instance, this command can be run-length encoding or TIFF
2	Tagged Image File Format (TIFF)	encoding.
	byte	Note: For further information, see “Raster Compression Mode” on
3	Delta Row
		page 2-88and “Group 3 and Group 4 Raster Compression” on
5	Adaptive Compression
		page 2-93.
9	Replacement Delta Row
999	Zlib
1002	Group 4

1004	Group 3 two dimensional K=2
1005	Group 3 two dimensional K=4
1006	TIFF word (16 bit)
1007	TIFF double-word (32 bit)

ESC*b#W[data]		Transfer Raster Data by Row/Block
# = Number of Data Bytes		Transfers RIG data.
		Note: After each command, the cursor position is moved to the
		beginning of the next raster row.
ESC*rB		End Raster Graphics (Version B)
		Signals end of raster graphics transfer. If a Raster Height is
		specified, the cursor is moved to the first raster row past the Raster
		Height.
ESC*rC		End Raster Graphics (Version C)
		Same as Version B, but:
		• Resets compression mode to uncoded.
		• Sets left graphics margin to 0.
ESC*t#H		Raster Width (Destination)
		Sets the width of the destination raster.
