There is a faster way to do this in WP9, without getting into logical page size or copy and paste.
Click on the "Perfect Expert" button.
Click on "Start", "New Project". This brings up Perfect Expert. Under WordPerfect heading, click "Labels", then "Create". Now, click "Choose Size", I use one of the Avery Business Card (5 up) sizes, as they are standard size. Create your card and then click the button on the left marked "Fill Entire Sheet". WP fills the page, ready for printing pre-perforated business card sheets.
