Print single-density image

EscKn
1
This command enables you to define and print a single line raster bit image on a single text line.
n and n
1
The image consists of 256*n
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.
Images are printed from left to right.
Images are printed at a horizontal resolution of 60 dots per inch and at an approximate vertical resolution of
72 dots per inch.
You can only use this command in portrait orientation.
