Line Spacing n/216 Inch

ASCII Code SFCC 3 n

Hex Code	SFCC 33 n
Dec Code	SFCC 51 n
Purpose	Specifies the line spacing at n/216-inch increments.
where:	n = 1 through 255 (hex 01 through hex FF)
Comment	When the n/216-inch line spacing control code is received, all
	line feeds following are at n/216-inch line spacing until a new line
	spacing is selected or the printer is reset. The control code line
	spacing selection overrides the control panel line spacing
	setting.
	The vertical character position moves only in multiples of the
	current dot row spacing. If the distance to move is other than a
	multiple of the current dot row spacing, the remainder is added
	to the next paper motion command.
	Caution should be used when combining this control code with
	other print attributes such as Elongated (Double High),
	Superscript, or Subscript; overlapping lines may occur. Printing
	at different horizontal and vertical densities do not overlap.
Example	The following example illustrates n/216-inch line spacing.

Overscoring

ASCII Code SFCC _ n

Hex Code	SFCC 5F n
Dec Code	SFCC 95 n
Purpose	Enables or disables automatic overscoring of all characters.
where:	n = 0 to disable automatic overscoring (hex 00 or hex 30)
	n = 1 to enable automatic overscoring (hex 01 or hex 31)
Comment	When automatic overscore is enabled, all characters, including
	spaces, are overscored until disabled.
Example	The following sample illustrates automatic overscoring and
	overscoring reset.
