Form Feed
ASCII Code FF
Hex Code 0C
Dec Code 12
Purpose Prints the data in the buffer, advances the paper position to the
next top-of-form, and moves the character position to the first
character column.
Comment The default forms length is determined by the configuration in
nonvolatile memory. Forms length is set by using the control
panel or forms length control codes. Code FF cancels all single-
line only print attributes.
The Form Feed command reacts differently when the VFU is
active. See Chapter 9, “Vertical Page Formatting.”

=whole numbers from 1 through 21 (hex 01 through hex 15) to
specify the number of inches on a page.
Comment Upon receipt of this code, the current line becomes the first line
of the form, and the form length set becomes the current forms
length. Vertical tab positions set below the bottom of the form
are ignored.
Forms length is defined in inches; therefore, subsequent line
spacing changes do not affect the result of this command.
The maximumforms length is 21 inches. All larger valuesare
ignored.
When forms length is changed by the ESC C NUL sequence, the
bottom margin is set to zero. If the product of lines and line
spacing (forms length) is not an exact multiple of the printer dot
resolution, the value is adjusted down until forms length and dot
resolution distance match.
The current paper position becomes top of form. If the form
length is set smaller than the line spacing, a line feed moves the
current line spacing; a form feed advances paper position to the
next top-of-form position.
Forms length can also be set through the control panel. The
control code forms length setting from the host computer
overrides the control panel setting.
