Hmmm interesting. The device certainly does appear to impact the .pdf export. The Page Size property of the .pdf generated from my iPad show the dimensions as 17.78 x 31.72 while a .pdf generated from my Android phone has a Page Size of 15 X 23.67 which translates to 6.97 X 11 so it's using more of the width.

There is no option to export to an Image on the iPad but there is on the phone. Is that export option specific to Android? If that option were available on my iPad I'd be set.

Thanks for your input sciurius.
