•This command enables you to define and print a single line raster bit image on a single text line.

•n1 and n2 define the number of bytes that comprise the image.

•The image consists of 256*n1+n2 bytes of data, each byte representing a single vertical column of 4/30".

•Images are printed left to right.

•Images are printed at an approximate horizontal resolution of 240 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.
