Displaying margins
The viewers also provide the option to display or hide margins for any report design you are viewing. Selecting or deselecting this option displays or hides margins in the browser window, and does not impact page margins when printing a report design or exporting a report design to other formats.
To display a margin, choose Show Margin from the main menu.
To hide a margin, choose Hide Margin from the main menu.
