Epson FX Emulation9–14
Set Page Length by Lines
ASCII Code ESC C n
HEX Code 1B 43 n
Purpose Sets the page length by lines.
where n = hex 1 to hex 7F, to specify the number of lines per page at the
current line spacing.
Comment The current line becomes the first line of the form. The forms length
units are always defined in inches; therefore, subsequent line spacing
changes do not affect the result of this command. Changing lpi does
not change the forms length.
The forms length is set to the number of lines defined by the quotient
of n and the current line spacing so that the units are in inches.
If the calculated forms length in lines is not an exact multiple of the
target machine dot size, the forms length value will be 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.
