Sets the left margin of the printing area. The left margin 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), described in this manual.
The width of the printing area is set by the Set Printing Area Width command (1D 57),
which follows this command. See the Set Printing Area Width command in this
document for a description of that command.
If the setting exceeds the printable area, the maximum value of the printable area is
used. The maximum printable area is 576 dots. See the illustration.
To set the left margin to one inch at the default horizontal motion unit of 1/203 inches,
send the four-byte string:
GS L 203 0
Or, to set the left margin to two inches at the default horizontal motion unit of 1/203
units per inch, send the four-byte string:
GS L 150 1
Where 2 inches = 406/203, and 406 = (1 X 256) + 150.
