Event handler to be called when a user invokes the Page Setup… command from Internet Explorer's File menu.
You may cancel this operation within the event handler simply by returning, or you may call PageSetup to provide the expected behavior.
In the latter case, once the user has made changes on the Page Setup dialog an onpagesetup event will be fired to update the page's user interface.
This is a read/write property.
