*Segment Size (UI) - indicates the size of each item in the data segment. 
*Data segment - 
AP -  Application support segment  (reserved) 
CC -  Character Complement 
  Function and form are as same as character complement flag in the font descriptor.  This is only for 
unbound fonts. 
CP -  Copyright 
  Value should be ASCII data. 
GI -  Global Intellifont data (reserved) 
GT -   Global TrueType Data 
  This segment consists of a table directory and several tables for the TrueType font scaler. 
  The table directory consists of a 12-byte header and 16 bytes pen entry.    
IF -  Intellifont Face Data (Reserved) 
PA -  PANOSE Descriptor  
  This data segment is used for font selection and substitution. 
PF -  PS-compatible font name (Reserved) 
XW -  X-Windows font name 
 
5.4.4.  Sending a character code 
Esc*c#E (character code)  (27)(42)(99)#(69) 
 <1Bh><2Ah><63h>#<45h> 
 
This command sends a character code for the bitmap font ( MSL number for unbound fonts )  to the printer. 
The font data must follow immediately. 
  # is the character code. # can be from 0 to 65535.  The specified character is defined by the data which 
follows the character code. 
  Use this command also to designate a character for deletion from a font, using the command for deleting a 
character from a downloaded font. 
 
5.4.5.  Sending a character descriptor and data 
Esc(s#W (character descriptor and character data)   
 (27)(40)(115)#(87)   <1Bh><28h><73h>#<57h> 
 
This command sends a character descriptor block and raster data describing the shape of the character to the 
printer. 
  # is the total number of bytes (descriptor and data) which will follow this command and can be up to 32767. 
If you need to send more than 32767 bytes to describe a single character you must split it into blocks of 
32767 bytes or less and send each block separately.  
  The character header for the first block of data describing a character is in the following format. 
 
[Bitmap font ] 
Byte Data   
0 - 1  Format  Continuation 
2 - 3  Descriptor size  Class 
4 - 5  Orientation  Reserved 
6 - 7  Left offset   
8 - 9  Top offset   
10 - 11  Character width   
12 - 13  Character height    
14 - 15  Delta X   
16 -  Raster Character Data
