The image consists of 256*n
4/30".
Images are printed left to right.
Images are printed at an approximate horizontal resolution of 240 dots per inch and at an approximate
vertical resolution of 72 dots per inch.
Each byte represents a vertical column of eight dots, the most significant bit representing the dot at
the top. Simply set a bit to 1 if you want a dot to appear in that position, and to 0 if you want white
space to appear.
