Chapter 4 Configuring the Serial MatrixEmulation with Control Codes
Line Spacing 7/72Inch
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
10.3lines 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.

Purpose Stores a line spacing of
n
/72-inchincrements.
where:
n
=1 through 85 (all others are ignored)
Comment When the ESC A control sequence is received, all line feed
commands following an ESC 2 sequence are at
n
/72-inchline
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.
Small values of
n
may result in overlapping lines. Overlapping
lines may also occur if print attributes such as Elongated
(Double High), Superscript, or Subscript characters are used on
the same line. Printing at different horizontal and vertical
densities do not overlap.
Example The following example illustrates 20/72-inch line spacing.
