This example demonstrates the Active Frame Preview capability of the Feature Set #2 provided by MeadCo's MaxiPT print template.
Invoke Print Preview here or from IE's native controls to see it in action. You can view the source of this example here.
Preview Active Frame
This functionality allows you to specify that the active frame (if any) should be previewed instead of the main document.
When in Print Preview you can switch between Page and Frame previews by toggling the Show Page / Show Frame button on the preview pane's toolbar.
To disable this button (i.e. to prevent your users from making changes from the Preview pane), set this printingRule:
allowSwitchActiveFrame: false
Preview Active Frame can be set directly from script thus:
document.printingRules.useActiveFrame = true;
