This printer always prints as fast as possible, hence this command is the exact equivalent of
the Esc L command.

The image consists of 256*n
column of 4/30".
Ÿ
Images are printed left to right.
Ÿ
Images are printed at an approximate horizontal resolution of 240 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.
