ASCII Code ESC S n
HEX Code 1B 53 n

where n = NUL (hex 00) or 0 (hex 30) to enable superscript
printing

Comment Superscript prints full–sized characters 3/72 inch higher than the
normal characters. Subscript prints full–sized characters 3/72 inch
lower than the normal characters. When the control code is received,
all characters are superscript or subscript until reset by ESC T or
printer reset.
You can print both superscript and subscript characters in the same
character column by using the Backspace (BS) control code, but
these characters will not print when double high printing is in effect.
Example The following program illustrates superscript and subscript printing.
