Miscellaneous Function Commands
The TM-U950/U950P supports the following miscellaneous function commands.
Command Name

GS P x y
[Name] Set horizontal and vertical motion units
[Format] ASCII GS P xy

[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=150 and y=144. The calculated result
when using this command and the line spacing command is truncated to the minimum value of the
mechanical pitch (1/150 inch horizontal and 1/144 inch vertical) or an exact multiple of that
minimum value. The horizontal value 1/150 inch and the vertical value 1/144 inch each correspond
to a half-dot pitch.
Commands used with the horizontal motion unit (1/x): ESC SP, ESC $, ESC \
Commands used with the vertical motion unit (1/y ): ESC 3, ESC J, ESC K
