• 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

+n
1
bytes of data, each byte representing a single vertical column of
4/30".
• 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.
