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.

Esc(s#W (character descriptor and character data)
(27)(40)(115)#(87)
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 ]
Character Complement
Function and form are as same as character complement flag in the font descriptor. This is only for
