The image consists of 256*n
of 4/30".
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.
Ÿ
Images are printed from 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
You can only use this command in portrait orientation.
Ÿ
The printer always prints as fast as possible, hence this command is the exact equivalent of
the Esc L command.
