I assume you are using normal Mendix pages and a browser to show/export/print these pages. Then, the conditional visibility and access rules are applied based on the user you logged in with at that time. The “hidden” data is not available for you and also not exportable, printable or easily made visible.
When you use document templates the access rules are applied. So the print only contains the things the user is allowed to see.
