Setting Top/Bottom Margins
Using dot values to identify maximum vertical print positions, the page
boundary parameters of an 11–inch form has 792 dot rows at n/72–inch
vertically (72 dpi X 11 inches). (See Figure C–1.)
With no Top/Bottom Margin configuration setting on an 11–inch form, the
first print position is Starting Row 1, Starting Column 1 (A, Figure C–1).
However, if a Top/Bottom Margin value is set at 10, then Starting Row 1 is
adjusted down by 10 dot rows (B, Figure C–1), and the Ending Row is
adjusted up 10 dot rows (C, Figure C–1), thereby reducing the maximum
vertical printable area to 773 dots (793 – [10 + 10]). The greater the
top/bottom margin setting, the smaller the printable area on the form.
