Browse source 
TP:
Command: C0 1F Byte[0] Byte[1]
Byte[0] Device posture:
	0x00 portrait(Default)
        0x01 90 degrees right rotation
        0x02 90 degrees left rotation
Byte[1] Suppression area
	0x00 normal (0 pixel)(Default)
        0x01 Small area suppression (R-200 quadrant Pixel)
        0x02 Larger area suppression (R-250 quadrant Pixel)
