Bit-Image Commands
Function Select Bit-Image Mode
ASCII [ESC] * <m> <nl> <nh> <dl> … <dk>
Hexadecimal 1BH 2AH <m> <nl> <nh> <dl> … <dk>
Decimal <27> <42> <m> <nl> <nh> <dl> … <dk>
Range <m> = 0, 1, 32, 33
0 ≤ nl ≤ 255
0 ≤ nh ≤ 3
0 ≤ d ≤ 255
k = nl + nh x 256 for <m> = 0 or 1
k = (nl + nh x 256) * 3 for <m> = 32 or 33
Description [ESC] * <m> <n

n
h
x 256)*3 in mode 32 or 33 and <d> indicates the bit image data. Set a bit to
one to print a dot, or set a bit to zero to not print a dot. Use the command to print
a predefined picture or logo. The modes selectable by <m> are listed below.
