GS P x y
[Function] Specifying the basic calculation pitch
[Code] <1D>H<50>H<x><y>
[Range] 0 x 255
0 y 255
[Outline] • This command sets the horizontal basic calculation pitch to approx. 25.4/x mm (1/
x inches), and the vertical basic calculation pitch to approx. 25.4/y mm (1/y inches).
• If x = 0, the horizontal basic calculation pitch is reverted to the default value.
• If y = 0, the vertical basic calculation pitch is reverted to the default value.
[Caution] • The horizontal direction is defined as the direction perpendicular to the paper feed,
and the vertical direction is defined as the paper feed direction.
• In STANDARD MODE, the following parameters are used regardless of the character
orientation (e.g. inverted or 90°-right-turned).
(1) Commands using x: ESC SP, ESC $, ESC \, FS S, GS L, GS W
(2) Commands using y: ESC 3, ESC J
• In PAGE MODE, the parameters used depend on the character orientation, as follows:
(1) If the start point specified by ESC T is the top left or bottom right (The characters
are mapped in the direction perpendicular to the paper feed):
• Commands using x: ESC SP, ESC $, ESC W, ESC \, FS S
• Commands using y: ESC 3, ESC J, ESC W, GS $, GS \
(2) If the start point specified by ESC T is the top right or bottom left (The characters
are mapped in the paper feed direction):
• Commands using x: ESC 3, ESC J, ESC W, GS $, GS \
• Commands using y: ESC SP, ESC $, ESC W, ESC \, FS S
• This command does not affect any other values that are already set.
• If calculations made in combination with another command generate fractions,
the fractions are corrected with the minimum pitch of the mechanism, and the
remainder is omitted.
[Default] x = 203, y = 360
