Formulas
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.
Exceptions:
The command is effective only at the beginning of a line.
This command is ignored if the line buffer is not empty,
and only effects the receipt interface.
