MARGINS
	ESC X				Set Horizontal Margins
	ASCII:	ESC	X	(n1)	(n2)
	Control:	CTRL [	X	(n1)	(n2)
	Decimal:	27	88	(n1)	(n2)
	Hexadecimal:	1B	58	(n1)	(n2)

Sets the left margin to Column n1 and the right margin to Column n2. Specify margins in character positions, at the pitch currently in use. Margins are stored in absolute displacements from the left edge of the paper.

If n1 is 0, the current left margin is used. If n2 is 0, the current right margin is used.

n1 must be at least one character position less than n2.

n2 must be 255 or less. If 255 is specified for the right margin, the maximum right margin is set.

Use a CR immediately after ESC X to establish the printhead position relative to the new margin settings.
