SFCC A n
ESC A n
Stores a line spacing of n/72–inch increments.
n = 1 to 85 (all others are ignored)
When the ESC A control sequence is received, all line feed commands following an
ESC 2 sequence* are at n/72–inch line spacing until a new line spacing is selected or
the power is reset. The control code line spacing selection overrides the control
panel line spacing setting and the message display reflects the line spacing in lines
per inch. For the 20/72–inch example below, the message display would reflect 3.6
lpi spacing.
*The SFCC/ESC 2 sequence (page 6–47) asserts the line spacing which was stored
by the preceding SFCC/ESC A sequence.
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 char-
acters are used on the same line. Printing at different horizontal and vertical densi-
ties does not cause overlapping.
The following example illustrates 20/72–inch line spacing.
