5.1.1 Preview

The Preview pane contains a positioning widget that allows interactively positioning the output on the page. It contains an outer border, representing the sheet of paper; an inner border, representing the printable area of the printer; an arrow, pointing to the top of the page (the end that's fed into the printer); and a black rectangle, representing the position of the image on the page. The image can be moved around on the paper. When the first (left) button is used, the image is moved in screen pixels; when any other button is used, the image is moved in points(2). The arrow resizes depending upon the media size chosen; the shaft of the arrow is always equal to one inch on the output.
