Chapter 5 Configuring the Proprinter III XL Emulation with Control Codes

Line Spacing n/216 Inch

ASCII Code ESC 3 n

Hex Code	1B 33 n
Dec Code	27 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.

Margins, Left/Right, Set

ASCII Code ESC X n1 n2

Hex Code	1B 58 n1 n2
Dec Code	27 88 n1 n2
Purpose	Sets the left (n1) and right (n2) margins.

n1 and n2 are the margin positions (in character columns), which are based on the current cpi. They have a range of 1 through

255.Any value that sets the right margin beyond the form width is ignored.

where:	if n1	= 0, the left margin is unaffected.
	if n2	= 0, the right margin is unaffected.
