	Hexadecimal	1B	57	xL	xH	yL	yH	dxL	dxH	dyL	dyH
	Decimal	27	87	xL	xH	yL	yH	dxL	dxH	dyL	dyH

[Range]	0	xL 255, xH = 0, 0 yL 255, 0 yH 1, 0 dxL 255, dxH = 0
	0	dyL 255, 0 dyH 1 (Except dxL = dxH = 0 or dyL = dyH = 0)
[Outline]	This command sets the position and size of the print area in the page mode.

•The upper left start point is represented by (x0, y0), y-directional(vertical) length by dy dots, and x-directional(horizontal) length by dx dots.

x0	= [(xL + xH ⋅ 256)]	y0 = [(yL + yH ⋅ 256)]
dx	= [(dxL + dxH ⋅ 256)]	dy = [(dyL + dyH ⋅ 256)]

				(209 dots, 479 dots)
[Caution]	•	Setting beyond the printable area on the paper is automatically adjusted to the maximum
		settable area, based on the effective values from xL to dyH (i.e., xL, xH, yL, yH, dxL, dxH,
		dyL and dyH).
	•	The maximum x-directional dot in the printable area is 210.
	•	The maximum y-directional dot in the printable area is 480.
	•	When deploying the print data in the speciﬁed area, a print area length in the character
		printing direction and vertical direction must be always 8 dots or more.
	•	Set the print area to the size ﬁttable within the printing paper.
	•	If the start point (x0, y0) is beyond the printable area, this command will be ignored.
	•	Only setting is valid in the standard mode.
[Default]	xL = xH = yL = yH = 0, dxL = 210,
	dxH = 0, dyL = 224, dyH = 1
