Form Feed

ASCII Code FF

Hex Code 0C

Dec Code 12

Purpose Prints the data in the buffer, advances the paper to the next top-

of-form, and moves the logical printhead to the first character

column.

Discussion Forms length is set by using the control panel or forms length

control codes. This code cancels double wide (expanded)

characters if set by the SO command. The Form Feed command

will react differently when the VFU is active. Refer to Chapter 6

in this manual for further information. The Form Feed command

will react differently when the control panel selection “FF Valid at

TOF” is disabled. Refer to the

User’s Manual

for further

information.

Forms Length Set in Inches

ASCII Code ESC C NUL

Hex Code 1B 43 00

Dec Code 27 67 0

Purpose Sets the length of forms (paper) in inches.

where

= whole numbers from 1 through 21 (hex 01 through 15) to

specify the number of inches on a page. (All larger values are

ignored.)

Discussion Upon receipt of this code, the current line becomes the first line

of the form, and the forms length set becomes the current forms

length. Vertical tab positions set below the bottom of the form

are ignored; in addition, once a new forms length is set the

bottom margin is set to zero.

Line spacing changes do not affect the result of this command. If

the forms length is set smaller than the line spacing, a form feed

advances the paper position to the next top-of-form position.

Forms length in inches can also be set at the control panel via

the LinePrinter+ Form Length menu option (refer to the

User’s

Manual

). However, this host control code overrides the control

panel setting.
