Variable image Data not Printing to PDF

I use Printshop Mail version 6.1 and Adobe Acrobat pro XI. I created a document using variable data, an image background, and variable image data. When I print to any of my presses it all comes out fine. Print preview looks fine as well. However when I print to PDF everything but the variable image data prints. It doesn't matter what file format I use for the variable data either. Thank you so much for your help.
