Bottom Margin Set
ASCII Code ESC N n
Hex Code 1B 4E n
Dec Code 27 78 n
Purpose Sets the bottom margin.
Discussion n defines the number of lines above the bottom of the form to set as the
bottom margin. n has a range from 1 through 255.
If a line feed command causes the active position to advance below the
bottom margin, the paper advances to the top of the next form. If the page
length is equal to or greater than the form length, the length is reset to the
length of the form. If the forms length is changed by the ESC C code (Forms
Length sequence), the bottom margin is set to zero.
An ESC N code can occur at any place in the datastream and is acted upon
immediately. All control codes that define vertical distance expressed in
inches are stored internally in units of paper drive steps.

Hex Code 1B 4F
Dec Code 27 79
