EscKn1n2<image data>

(27)(75)n1n2....

<1Bh><4Bh>n1n2....

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*n2+n1 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.
