The Printable Area is a rectangular area located inside the Workspace. The color of this area is set by the Window Background color. You can set this color using the Windows Control Panel Colors. The Printable Area indicates boundaries of your printable output document. The divider lines surrounding this rectangular area define exact printing boundaries. If you create a multi-page document, such as a tiled banner or a poster three pages high and four pages long, the divider lines will show printable area page layout for the entire banner or poster. You can change the layout by setting correct options in the Page Setup dialog box. This dialog box is displayed when you click File > Page Setup. Each Output Type has its specific size of Printable Area.
