[Description]	•	The horizontal starting position, vertical starting position, printing area width, and printing area
		height are defined as x0, y0, dx, dy, respectively.
		Each setting for the printing area is calculated as follows:
		x0 = [(xL + xH ⋅	256) ⋅		(horizontal motion unit)]
		y0 = [(yL + yH ⋅	256) ⋅		(vertical motion unit)]
		dx = [dxL + dxH ⋅		256] ⋅		(horizontal motion unit)]
		dy = [dyL + dyH ⋅		256) ⋅		(vertical motion unit)]
		The printing area is set as shown in the figure below.
[Details]	•	If this command is input in standard mode, the printer executes only internal flag operation.
		This command does not affect printing in standard mode.
	•	If the horizontal or vertical starting position is set outside the printable area, the printer stops
		command processing and processes the following data as normal data.
	•	If the printing area width or height is set to 0, the printer stops command processing and
		processes the following data as normal data.
	•	This command sets the position where data is buffered to the position specified by ESC T
		within the printing area.
	•	If (horizontal starting position + printing area width) exceeds the printable area, the printing
		area width is automatically set to (horizontal printable area - horizontal starting position).
	•	If (vertical starting position + printing area height) exceeds the printable area, the printing area
		height is automatically set to (vertical printable area - vertical starting position).
	•	The horizontal and vertical motion unit are specified by GS P. Changing the horizontal or
		vertical motion unit does not affect the current printing area.
	•	The GS P command can change the horizontal (and vertical) motion unit. However, the
		value cannot be less than the minimum horizontal movement amount, and it must be in even
		units of minimum horizontal movement amount.
	•	Use the horizontal motion unit (x) for setting the horizontal starting position and printing area
		width, and use the vertical motion unit (y) for setting the vertical starting position and printing
		area height.
	•	When the horizontal starting position , vertical starting position, printing area width, and
		printing area height are defined as X, Y, Dx, and Dy respectively, the printing area is set as
		shown in the figure below.
