Forms Length Set (Lines)
ASCII Code ESC C n
Hex Code 1B 43 n
Dec Code 27 67 n
Purpose Sets the length of a form (paper) in lines.
Discussion When forms length is set by the ESC C n sequence, it is the product of
the parameter n and the current line spacing. The range of n is 1 through
the total number of lines that total 21 inches at the current line spacing.
When necessary, the form length is rounded to the nearest dot row
position.
If the page length is set smaller than the line spacing, a line feed moves the
current line spacing and a form feed advances paper to the next top–of–form
position.
A line spacing change does not affect the forms length. If forms length is set
with the ESC C code, it becomes the current forms length and the bottom
margin is set to zero.
If the calculated forms length in lines is not an exact multiple of the paper
step distance, the forms length value will be adjusted down to the next
possible multiple.
A Forms Length Set code can occur at any place in the datastream and is
acted upon immediately. All control codes that define vertical distance
expressed in inches are stored internally in units of paper drive steps.
NOTE: To check the exact value of the current forms length with the printer
off–line, activate the forms length setting on the operator panel.
