Hi,

The best suggestion I can come up with is copy the printerfriendly skin and rename it, then remove things like site heading and footer stuff from the layout.master of the copied skin and then set that as the skin for the page that has Form Wizard on it. If you haven't already you'll need to enable page level skins from site settings in order to be able to assign a specific skin to the page.

Be careful not to remove anything that is required from the layout.master file, if you remove something required it will cause an error to be logged and it will fallback to a failsafe master page. You should be able to remove things like the site heading, footer topnav links, and menus but you cannot remove things like divLeft, divRight, divCenter, contentpalceholders, StyleSheetCombiner, ScriptLoader

You'll probably also want to set that page as not included in the menu and site map from page settings so users don't find it outside your popup since it won't look like other pages in the site.

Hope that helps,

Joe
