GS L nL nH
[Function] Setting the left margin
[Code] <1D>H<4C>H<nL><nH>
[Range] 0 nL 255
0 nH 255
[Outline] This command sets the left margin specified by nL and nH.
The value of the left margin is [(nL + nH × 256) × basic calculation pitch] inches.
[Caution] • This command only works when it is entered at the beginning of a line.
• When PAGE MODE is selected, this command only executes the internal flagging
of the printer.
• The setting of this command does not affect PAGE MODE.
• The maximum settable left margin is equal to the horizontal printable area. A
setting greater than this maximum is trimmed to the maximum.
• The basic calculation pitch is defined by GS P. Once defined, the left margin is not
changed if the basic calculation pitch is changed by GS P.
• The left margin is calculated with the horizontal basic calculation pitch (x) set by
GS P. A fraction resulting from the calculation is corrected with the minimum pitch
of the mechanism, and the remainder is omitted.
• When mapping character data, if the print area specified is not wide enough to
accommodate one character of the current font, only the line for that character
data is handled as follows:
(1) The print area is extended toward the right to be equivalent to one character of
the current font, but not wider than the printable area.
(2) If an area for one character cannot be provided as a result of step (1), the print
area is extended toward the left. (So, the left margin is decreased.)
• When mapping non-character data (bit image, downloaded bit image, or bar code),
if the print area specified is narrower than 9-bits, only the line for that data is handled
as follows:
(1) The print area is extended toward the left (so, the left margin is decreased)
until it is 9-dot wide, but not wider than the printable area.
[Default] nL = 0, nH = 0
