[Function] Correcting the leader position of Black mark paper/ label paper
[Code] < 1D>H<41>H
[Range] 0≦m≦255
0≦n≦255
[Outline] [The specification which is common to the model]
This command sets the leader position of Black mark paper/ label paper in terms of correction value
set for the default position.
“m” denotes the correcting direction.
• “m” is valid only for the lowest bit (m0).
• Control by the lowest bit (m0) is shown as follows:
Correcting Direction m0
0 Corrects the leader position in the forward direction
1 Corrects the leader position in the reverse direction
• “n” denotes the correction value in units of n/203 inch.
[Caution] • This command is valid only when Black mark paper/ label paper is chosen.
• This command is ignored except immediately after the execution of a Black mark/ label positioning
command (FF, GS FF, GS A, GS <) or immediately after leader positioning performed on a paper
feed action with the FEED switch, power on, or cover closure.
• The maximum reverse correction span is 0.5 mm. Correction settings exceeding this value are
truncated into the maximum value. The leader position may be deviated due to paper flexure. For
reverse correction, exercise care so the leader position does not step out of the Black mark/ label.
• For forward correction, set the correction span by taking into account the Black mark/ label length
as the printable area changes before and after correction setting.
• In calculating a correction span, use the basic calculation pitch (y) for the vertical direction. The
fractional part contained in the calculation result should be corrected in units of the mechanism’s
minimum pitch, with the remaining fractional part truncated.
