Set Margin, Left

Set Margin, Left

ASCII Code ESC l n

Hex Code	1B 6C n
Dec Code	27 108 n
where:	n = number of columns from the left edge of the physical page to
	the beginning of the print line;
	n = 1 through 232 (hex 00 through hex E8)
Purpose	Sets the left margin to n columns in the current font.
Comment	Be sure to use the alphabetic lowercase “l” (as in left) rather than
	the uppercase i “I” for this command. The number of inches of
	margin does not vary if the font, character width, or horizontal
	dot density changes. This command automatically clears and
	resets horizontal tabs to every eight characters. The smallest
	possible space between the left and right margins is the width of
	one double-wide, 10 cpi character. If a margin control code
	violates this minimum distance, it is ignored. Settings in
	proportional mode are treated as 10 cpi.

Set Margin, Right

ASCII Code ESC Q n

Hex Code	1B 51 n
Dec Code	27 81 n
where:	n = number of columns from the left edge of the physical page to
	the end of the print line;

Purpose	Sets the right margin to n columns at the current character width.
Comment	The number of inches of margin does not vary if the font,
	character width, or horizontal dot density changes. This
	command automatically clears and resets horizontal tabs to
	every eight characters. The smallest possible space between
	the left and right margins is the width of one-double wide, 10 cpi
	character. If a margin control code violates this minimum
	distance, it is ignored. Settings in proportional mode are treated
