Print double-speed double-density image
EscYn n <image data>
1 2
• 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.
1 2
• The image consists of 256*n
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 an approximate horizontal resolution of 120 dots per inch and at an approximate
vertical resolution of 72 dots per inch.
• You can only use this command in portrait orientation.
• The printer always prints as fast as possible, hence this command is the exact equivalent of the Esc L
command.
