ESC 3 n
[Designation] Set line spacing
[Format] 1BH, 33H, n
[Valid limits] 0 n 255
[Initial value] n = 60
[Function] (1) Sets the line feed amount per line to [n×basic calculated pitch]inches.
(2) The line feed amount can be set up separately for standard mode and page
mode.
(3) The basic calculated pitch is set up using the Set horizontal and vertical motion
unit command (GS P).
Furthermore, the specified line feed amount will not be changed even if the
basic calculated pitch is changed using the Set horizontal and vertical motion
unit command (GS P) after the line feed amount has been set up.
(4) If the calculation result contains a fraction, the value is corrected using the
minimum pitch of the mechanism. The remainder is then discarded.
(5) In standard mode, the vertical motion unit (y) is used.
(6) In page mode, the operations given below are executed based on the starting
point:
a. The vertical motion unit (y) is used if the starting point has been specified as
upper left or lower right using the Select print direction in page mode
command (ESC T).
b. The horizontal motion unit (x) is used if the starting point has been specified
as upper right or lower left using the Select print direction in page mode
command (ESC T).
(7) Up to about 900 mm (35.4 inches) of line feed increments can be set. If the
maximum value is exceeded, the value will be rounded off to the maximum
value.
