Proportional Space Mode (ESC P)

Deselect on Positive Query Reply (ESC Q)
1B 51 NN
This control deselects the printer if the response to the query is positive.
NN is the query printer identifier. If the value matches the printer's ID, the query response is positive and
the printer deactivates the Select line. If the query is not positive, the control is ignored.
The printer must be reselected using a DC1 control after a positive response to ESC Q if the printer is to
be used.
Query Identifiers: If the emulation mode is set to 4202 III XL, the printer ID is X'16'. If the emulation
mode is set to 4247 or 2381, the printer ID is X'B8'.
Set Default Tabs (ESC R)
1B 52
This control resets both the horizontal and vertical tab stops. The horizontal tab stops are set to every
eighth position starting with the ninth column (9, 17, 25,...). The vertical tab stops are cleared.
Begin Subscript/Superscript (ESC S)
1B 53 NN
This control activates subscript and superscript printing. Once this printing is active, it stays active until
another Begin Subscript/Superscript control changes the mode, an End Subscript/Superscript control is
received, or the printer is initialized.
NN is a one-byte hexadecimal value that activates subscript or superscript printing.
v If NN is 1, subscript mode is active.
v If NN is 0, superscript mode is active.
