Skip-Over Perforation

ASCII Code ESC N n

Hex Code

1B 4E n

Dec Code

27 78 n

Purpose

Selects the number of lines (at the current line spacing) for the

 

paper to skip at the bottom of the perforated page.

where:

n = 1 through 127 (hex 01 through 7F) to select the number of

 

lines to skip. If the value of n exceeds the current form's length, it

 

is ignored.

Comment

The actual distance set is the product of n and the current line

 

spacing. Factory default value disables bottom margin. The

 

current default value may be set by the operator. Setting a new

 

forms length (ESC C) resets bottom margin to zero. This feature

 

is disabled whenever vertical tabs are set.

 

The bottom margin can also be selected from the control panel;

 

however, vertical tabs within the bottom margin zone, as set by

 

the control panel, are ignored. The control code bottom margin

 

setting from the host computer overrides the control panel

 

setting.
