ESC $ n1 n2
[Function] Specifying the absolute positions
[Code] <1B>H<24>H<n1><n2>
[Range] 0 n1 255
0 n2 255
[Outline] The printing start position is specified with the number of dots
(1/203 inch unit) from the beginning of a line.
• The number of dots is divided by 256, whose quotient is taken
as “n2” and the residual as “n1”.
• Therefore, the printing start position is equal to n1 + n2
×
256
from the beginning of a line.
[Caution] The basic calculation pitch is set by GS P. After the line feed
width is set, if the basic calculation by GS P leaves a fraction,
the fraction is corrected with the minimum pitch of the
mechanism, and the remainder is omitted.
In STANDARD MODE, this command uses the horizontal (Paper
feed direction) basic calculation pitch (x).
In PAGE MODE, this command acts differently depending on
the start point:
(1) If the start point specified by ESC T is top right or bottom
left, the command uses the vertical (Paper feed direction)
basic calculation pitch (y).
(2) If the start point specified by ESC T is top left or bottom
right , the command uses the horizontal (Perpendicular to
the paper feed direction) basic calculation pitch (x).
Specification beyond the end of the line is ignored.
[Default] The initial value is not defined.
