Set Left Margin

This command 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. Refer to Set Printing Area Width for a description of that command.
