Decimal 29 80 x y
[Range] 0 ≤ x ≤ 255
0 ≤ y ≤ 255
GS P x y sets the horizontal and vertical motion units to 1/x and 1/y inches, respectively. The
horizontal and vertical motion units indicate the minimum pitch used for calculating the values of
related commands (shown below). The default values are x=180 and y=360. These values equal a
normal dot pitch in horizontal and half dot pitch in vertical. When x and y are set to 0, the default
setting of each value is used.
Commands used with the horizontal motion unit (1/x) in standard mode: ESC SP, ESC $, ESC \,
GS L, and GS W.
Commands used with the vertical motion unit (1/y ) in standard mode: ESC 3, ESC J, and GS V.
