Chapter 5 Configuring the Proprinter III XL Emulation with Control Codes

Line Spacing 1/8 Inch (8 lpi)

ASCII Code ESC 0		ESC A n
Hex Code	1B 30
Dec Code	27 48
Purpose	Specifies continuous line spacing at 1/8-inch increments (8 lpi).
Comment	The value of n should be 9 if using ESC A n.
	When the 1/8-inch line spacing control code is received, all lines
	are printed at 8 lpi 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.
Example	The following example illustrates 1/8-inch line spacing.

Line Spacing 7/72 Inch (10.3 lpi)

ASCII Code ESC 1

Hex Code	1B 31
Dec Code	27 49
Purpose	Specifies the line spacing at 7/72-inch (10.3 lpi) increments.
Comment	When the 7/72-inch line spacing control code is received, all
	lines are printed at the 7/72-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, and the message display reflects the line spacing as
	10.3 lines per inch.
	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 7/72-inch line spacing.
