Set Printing Area Width
Hexadecimal:
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 (1D 4C...) earlier in this document for a description.
Formulas:
To set the width of the printing area to one inch at the default horizontal motion unit of
1/203 inches, send the four-byte string:
GS
Or, to set the width of the printing area to two inches at the default horizontal motion unit
of 1/203 units per inch, send the four-byte string:
GS
Where 2 inches = 406/203, and 406 = (1 X 256) + 150.
