Epson TM-T85P manual X0 = xL + xH 256 horizontal motion unit

	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.
[Notes]	• 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 horizlntal 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.
