on any printer without requiring the correct form length to be set. However, the correct form length should
always be set with the control panel setup. Even if the program does not use form feeds, the printer will
automatically scroll a completed form up to the tear bar to be torn off. This automatic scroll is based upon
form length. The easiest way to set form length is via the “Form Length” value in the forms menu, so it will be
correctly set for everyone using the form. If correct form length cannot be guaranteed from SETUP, then
each program should set the correct form length.
Set Form Length in Lines ESC C n
Sets the form length to n lines at the current line spacing. 1≥n≥255. Maximum form length is 37.9 inches.
Invalid form lengths will be ignored. Overrides the “Form Length” value in the forms menu.
For example, an 11 inch form contains 66 lines at 6 LPI, but 88 lines at 8 LPI. If line spacing is changed
after setting the form length, the physical form length (in inches) will not be changed.
Resets top of form to the current position, so it is wise to be at top of form before setting form length. Issuing
a form feed will guarantee this. Vertical margins are cleared.
Example: The following escape sequence will set form length to 66 lines. At 6 LPI, this will result in a form
length of 11 inches.
Escape sequence: ESC C 66

Set Form Length in Inches ESC C NUL n
Sets the form length to n inches. 1≥n≥37. Maximum form length is 37.9 inches. Invalid form lengths will be
ignored. Overrides the “Form Length” value in the forms menu.
Resets top of form to the current position, so it is wise to be at top of form before setting form length. Issuing
a form feed will guarantee this. Vertical margins are cleared.
Example: The following escape sequence will set form length to 11 inches, regardless of what line spacing is
set.
Escape sequence: ESC C NUL 11

Form Feed FF
Causes the current line to be printed, and then advances the paper to the top of the next form. If a top
margin is set, printing will continue at the top margin. Setting “Host FF at TOF” to “No” in the interface
setup menu allows a form feed to be ignored if the paper is already at top of form. If “Auto CR” is set to
“On” in the interface menu, a carriage return will also be performed.
