Chapter 6 Configuring the Epson FX-1050 Emulation with Control Codes

Set Forms Length by Lines

ASCII Code ESC C n

Hex Code	1B 43 n
Dec Code	27 67 n
Purpose	Sets the form length by lines.
where:	n = 1 through 192 (hex 01 through hex C0) to specify the number
	of lines per form at the current line spacing.
Comment	The forms length is set to the number of lines defined by the
	quotient of n divided by the current lines per inch so that the
	units are in inches.
	The current line becomes the first line of the form. The forms
	length is always defined in inches; therefore, changing the lpi
	after this control code has been issued does not change the
	forms length.
	If the calculated forms length in lines is not an exact multiple of
	the target machine dot size, the forms length value is adjusted
	down to the next possible multiple.
	When forms length is set by an ESC C sequence, the skip-over
	perforation set by ESC N is cancelled.

Set Forms Length in Inches

ASCII Code ESC C NUL n

Hex Code	1B 43 00 n
Dec Code	27 67 0 n
Purpose	Sets the form length to n inches.
where:	n = 1 through 24 (hex 01 through hex 18) to specify the number
	of inches on a form.
Comment	Upon receipt of this code, the current line becomes the first line
	of the form, and the form length set becomes the current forms
	length. Vertical tab positions set below the bottom of the form
	are ignored. Forms length is defined in inches; therefore,
	subsequent line spacing changes do not affect the result of this
	command.
	Values of n greater than 24 are ignored.
	When forms length is set by an ESC C NUL sequence, the skip-
	over perforation set by ESC N is cancelled.
	This control code overrides forms length set at the operator
	panel.
