CHAPTER 6 EPSON - 27 
Print double-speed double-density image 
EscYn

<image data>  (27)(89)n1n2.... <1Bh><59h>n1n2.... 
  This command enables you to define and print a single line raster bit image on a single text line.   
  n
1
 and n

 define the number of bytes that comprise the image. 
  The image consists of 256*n
2
+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 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.

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 240 dots per inch and at an approximate 
vertical resolution of 72 dots per inch. 
  You can only use this command in portrait orientation.
