horizontal graphic data. Where <color> is a byte that specifies the color
of the data being sent.
<color> =
0 Use Previously Selected Color
1 Red
2 Green

dot. While red, green, and blue pixels set to zero form a black dot. For
black print, one represents a black dot and zero represents a white dot.
Note 2
More than one color may be set at a time. Setting the color to six would
set green and blue simultaneously. Where <length> is a byte specifying
the length of the data including the format byte.
<length> =
0 to 254 (255 is reserved for future use.)
Where <format> is a byte specifying the format of the graphics data.
<format> =
0 for raw data
1 for bit wise RLE compression
8 for byte wise RLE compression
254 for difference compression
255 for same as previous scan line data
