Images are printed at an approximate horizontal resolution of 120 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.

This command enables you to define and print a single line raster bit image on a single text line.
n and n define the number of bytes that comprise the image.

The image consists of 256*n
Images are printed left to right.
Images are printed at an approximate horizontal resolution of 120 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.
This printer always prints as fast as possible, hence this command is the exact equivalent of the Esc L
command.
