I would like to print my PDF version of the form in two columns so it will fit on one page.

You can make a two columned form layout by shrinking the fields. Here's how: http://www.jotform.com/help/90-Field-Positioning

Then generate a PDF Form afterwards http://www.jotform.com/help/212-How-to-Create-a-PDF-Form.

If you need further help, let us know.
