GS W nL nH

[Name]	Set print area width
[Format]	ASCII	GS	W	nL	nH
	Hex	1D	57	nL	nH
	Decimal	29	87	nL	nH
[Range]	0 ≤ (nL + nH ⋅ 256) ≤ 65535				(0 ≤ nL ≤ 255 , 0 ≤ nH ≤ 255)
[Default]	(nL + nH ⋅ 256) = 512			(nL = 0 , nH = 2)
[Description]	• In standard mode, sets the print area width to [(nL + nH ⋅ 256) ⋅ (horizontal motion
	unit)].

GS \ nL nH

[Name]	Set relative vertical print position in page mode
[Format]	ASCII	GS	\	nL	nH
	Hex	1D	5C	nL	nH
	Decimal	29	92	nL	nH
[Range]	-32768 ≤ (nL + nH ⋅ 256) ≤ 32767
[Description]	• In page mode, moves the vertical print position to [(nL + nH ⋅ 256) ⋅ (vertical or
	horizontal motion unit)] from the current position.

•A positive number specifies downward movement, and a negative number specifies upward movement.

	m = 0, 1
[Description]	• Executes the macro that was defined with GS :.
	m					Operation

0Executes the macro r times continuously at an interval of [t ⋅ 100 ms].

1After waiting for [t ⋅ 100 ms], flashes the LED indicator and waits for the
