where
n may range from 0 through 255 (hex 00 through hex FF).
n = 1, 3, 5 (any odd value), selects subscript printing.
n = 0, 2, 4 (any even value), selects superscript printing.
Discussion When the super/subscript command is received, all characters
will be superscript or subscript until reset by the super/subscript
reset command or printer reset. Super/subscript print modes are
not available for the double high attribute.
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 sample illustrates superscript/subscript printing.

This code can occur at any place in the datastream and is acted
upon immediately.
Note Superscript and subscript characters print at the same size
as the current font, shifted up or down relative to the print
line.
