Hex Code 1B 41 n
Dec Code 27 65 n
Purpose Sets a line spacing of n /72 inch for subsequent line feeds.
where
n = 1 through 255 (hex 01 through hex FF).
Discussion When this control sequence is received, all subsequent line
feeds are
n /72-inch until a new line spacing is selected or the
printer is reset. This setting overrides line spacing set at the
control panel.
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. If lines overlap, printing speed is reduced. Any
values set by ESC 3 (line spacing
n /216 inch) are replaced.
Example The following example illustrates 20/72-inch line spacing.
