Displaying the print borders
Before printing a document, you might want to turn on the print borders so they are shown on the screen. You can then see how your document will be printed and whether it fits on the page. Most printers cannot print right to the edges of the paper so there is usually an area around the edge of the page you cannot print onto.
To display the print borders
From the Window menu, choose Show Print Borders.
Tips
The yellow (and green on a double page spread) rectangle represents the eLXs of the paper (This corresponds to the paper size defined in the Print Setup dialog) and the red (and blue on a double page spread) rectangle represents the area which can be printed.
The dark gray area around the outside is the area that will not be printed.
If no printer has been set up, no print borders are shown.
The print borders are not necessarily central on the paper (especially for ink jet printers).
