Form Length and Form Feed
Form length is the distance from the top of the form to the bottom of the form. A form feed will
advance the paper to the top of the next form. Some programs do not send form feeds. Instead, they
count line feeds, and send the appropriate number of line feeds to fill out the page. The usual rational
is that the program is then in complete control of form length, and will work 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 FF 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 “Forms 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.

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 setup menu, a carriage return will also be performed.

Horizontal Tabs
Default horizontal tab stops are set at every eighth column, i.e. column 8, 16, 24, 32, 40, etc. The
default tab stops are associated with columns, not absolute physical positions. Changing character
spacing will change the physical position of the default tab stops.
