Printing scale problems converting Powerpoint in Nitro v12

[Donna 0]

When I convert a Microsoft Powerpoint document to PDF the scale is all wrong, the print runs off of the edge of the page. I have tried using ppt's Print function, and by going into Nitro PDF and choosing to convert by adding the file. I have checked all through your support and product information and seeing nothing about this. Have checked print setting and is set to print one slide per page, but scale it is printing to PDF is likely 125%.  How can I make this scale to how it looks in the original program?
