Printer Drivers
On a folded sheet of paper with two page images, the horizontal distance from the
I
fold to the page image is called the gutter. You can set the gutter to zero, 50, 100, or
150 points.
When you fold several pages into a booklet, the thickness of the paper forces the page
I
image of the inner pages to shift slightly outward. The Creep control allows you to
choose a number of tenths of points by which to shift the page images inward to
compensate for the thickness of the paper. You can choose any value from zero to 20.
