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
