[Details] • This command is effective only processed at the beginning of the line in
standard mode.
• If this command is input in page mode, the printer performs only internal flag
operations.
• This command does not affect printing in page mode.
• If the setting exceeds the printable area, the maximum value of the printable
area is used.
• The horizontal and vertical motion units are specified by
GS P
. Changing the
horizontal and vertical motion unit does not affect the current left margin.
• The horizontal motion unit (x) is used for calculating the left margin. The
calculated result is truncated to the minimum value of the mechanical pitch.
