[Code]	<1D>H<3C>H
[Outline]	This command initializes the printer mechanism.
[Caution]	This command is valid only when the label printer is selected with DS1-5. Since it uses one
	label for scanning, a head search starts from the next label. The maximum label length and
	label spacing (Black mark) is 300 mm. Any label exceeding this limit results in an error.

GS A m n		(Only When Label Printer is Selected)
[Function]	Correctting the label top position
[Code]	<1D>H<41>H<m><n>
[Range]	0 ≤ m ≤ 255, 0 ≤ n ≤ 10
[Outline]	This command sets the label head search position in terms of correction value for the default
	position. m denotes the correcting direction and valid only for the least significant bit (m0).

	m 0	Correcting direction
	0	Corrects in the forward direction
	1	Corrects in the reverse direction
	n denotes a correction value; it is set in increments of n/203 inch.
[Caution]	This command is valid only when the label printer is selected with DS1-5. The correction
	value remains valid until it is re-set with this command or the power is turned on again. Any
	setting beyond the range is ignored.
