*Data segment -

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.

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 ]
