Set horizontal and vertical minimum motion units
ASCII GS P x y
Hexadecimal 1D 50 x y
Decimal 29 80 x y
Value of x: Horizontal
Value of y: Vertical
Range of x: 0 – 255
Range of y: 0 – 255
Default of x: Receipt: 203 Slip: 140
Default of y: Receipt: 203 Slip: 144
Sets the horizontal and vertical motion units to 1/x inch and 1/y inch respectively.
When x or y is set to 0, the default setting for that motion unit is used.

Set printing area width
ASCII GS W nL nH
Hexadecimal 1D 57 nL nH
Decimal 29 87 nL nH
Range of nL: 0–255
Range of nH: 0–255
Default: 576 dots (the maximum printable area)
Sets the width of the printing area. If the setting exceeds the printable area, the maximum value of the printable area
is used. The width of the printing area is set to ((nH X 256) + nL) times horizontal motion unit) inches. The horizontal
motion units are set by the set horizontal and vertical minimum motion units command (1D 50).
The width of the printing area follows the set left margin command (1D 4C). See the set left margin command
(10 4C …) earlier in this document for a description.
The command can be enabled or disabled for the slip. Default is disabled for the slip on A776, and enabled on B780.
