0 -1: Header size (UI) - set to 18 or greater.
This value stands for the number of header bytes.
2 -3 : Encoded Symbol Set Designator (UI) - should be as same as the ID code which is defined by ESC*c#R.
Format (UB) - 1 for MSL (Intellifont), 3 for Unicode (TrueType).
Symbol Set Type (UB) - 0, 1 or 2.
0 specifies a 7-bit font with character codes 20H to 7FH acceptable.
1 specifies an 8-bit font with character codes 20H to 7FH and 80H to FFH acceptable.
2 specifies 8-bit 256 all character fonts. Only when the printer is set to transparent print mode can the
characters 0, 7~15 and 27 be printed.
6 - 7: First Code (UI) - indicates the first code of definition data following this header.
8 -9: Last Code (UI) - indicates the last code of definition data following this header. This value should be
more than the first code value. Also, the data followed this header should have (Last code - first code +
10 - 17:
Character Requirement Flag ( 8 bytes )
Used in conjunction with the character complement field in the header of the font descriptor to decide the
compatibility of a symbol set for an unbound font. This flag indicates which symbol collections are
necessary to make the required symbol set.
Each bit in this field stands for the selection of each symbol collection. When set to 1, the symbol
collection is included and when set to 0, the symbol collection is not included in the unbound scalable
