bytes of data, each byte representing a single vertical
column of 4/30".
Ÿ Images are printed left to right.
Ÿ Images are printed at an approximate horizontal resolution of 120 dots per inch and at an
approximate vertical resolution of 72 dots per inch.
Ÿ 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.
