Character Descriptor and Data Format for 
Intellifont Scalable Fonts  
The character header contains a block of bytes that identify character 
outline data. Table 11-40 and Table 11-41 show the format of the 
Intellifont scalable character descriptor and data
.

Format (UB)
This is the first byte of every character data block header. It specifies 
the format of the character descriptor and data. The format number 
for Intellifont scalable fonts is 10.
If the format number is different from that expected by the device, the 
character is discarded.
 Continuation (B)
This is the second (and last) byte of every character data block 
header. It specifies whether the following data is the first (0) data 
block of a new character...

Class 3 -Intellifont Scalable Character Contour Data
Class 3 is for Intellifont scalable contour character data. The contour 
character data is organized as described in Table 11-41. Bytes 0-3 
contain the character descriptor.
Class 4 - Intellifont Scalable Compound Character 
Data
A class 4 character is a compound character and composition data 
follows. The composition data is organized as described in Table 
11-43. The compound descriptor allows combining two...

Character Intellifont Data Offset (SI)   
The offset to the Character Intellifont Data relative to the address of 
the Contour Data Size field.
Contour Tree Offset (SI)   
The offset to the contour Tree Data relative to the address of the 
Contour Data Size field.
XY Data Offset (SI)  
The offset to the XY data relative to the address of the Contour Data 
Size field.

Compound Character Escapement (SI)  
The escapement in design units of a compound character.
Number of Components (UB)   
The number of components of a compound character.
Component List   
This is a list of component descriptions. The list contains Number of 
Components elements. Each component descriptor consists of 6 
bytes as described in Table 11-46 below.
The Character Code is the character code number of a component of 
a compound character. X-offset is the...

Continuation (B)   
This is the second (and last) byte of every character data block 
header. It specifies whether the following data is the first (0) data 
block of a new character definition, or a continuation (1) block for a 
character definition which has already been received by the printer. 
Because the value field in a Character Definition command is limited 
to 32767 bytes, characters whose byte count exceed this must be 
sent in two or more blocks.
