Datamax-O'Neil VMP SERIES AN-16 (Single Byte Character Set Font File Format) - Manual (Page 5)

The letter "A" would need to allow for the increased cell size, and would become:
0000011000000000 -> 006h & 000h

FONT FILE EXAMPLE – VERSION 1.0 MONOSPACE:
Since the file must be in binary, it is often easiest to create using an assembler. The following example shows the header,
and two of the characters in a form ready to assemble. The object code output, then, can be sent to the printer using the
Oneil WINDOWS configuration program, or a special command.
dl PT10B_LINK ; Value is reset internally and can be any 4 byte number
db "1.0" ; font version number (1.0 flags this header and respresentation)
db 047H ; code resulting from mod 256 summation of name of font below
db "PT10B" ; name of this font
db 'E' ; single letter used as an alternate to refer to this font
db 00d ; use 00 for straight text
dw 14d ; (ABSOLUTE = 12) number of dots wide for this font
dw 20d ; number of dots high for this font
db 02d ; number of bytes in each dot row of each character
dw 40d ; number of bytes in each character represented in this font
db 'A' ; The letter "A" is first ASCII character represented
db 'B' ; The letter "B" is last ASCII character represented
db 00d ; reserved
db '1' ; USER font version number
db "04/30/96" ; USER font creation date
db "2 CHARS EXAMPLE FONT" ; USER 20 character description
