Configuring the Epson FX-1050 Emulation with Control Codes
Set Form Length in 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 C0) to specify the number of
lines per form at the current line spacing.
Discussion 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 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.
Set Intercharacter Spacing in 1/120 Inch
ASCII Code ESC SP n
Hex Code 1B 20
n
Dec Code 27 32 n
Purpose Permits character spacing adjustments in 1/120 inch increments.
where n = 0 through 127 (hex 00 through 7F).
Set Margin, Left
ASCII Code ESC l n (lowercase “L”)
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.
Discussion Be sure to use the alphabetic lowercase “L” (as in left) rather
than the numeral “1” (one) 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
