Data being printed is cropped on RHS.
Prints with large borders, and printed font seems large?
Partly alleviated by the changing of margins / fonts but awaiting uplink wx font dialog fix before completion.
An update on this issue!
With further testing, it appears our code is correct and should work on all platforms, however there is a bug in wxWidgets 2.8.10 on the Mac platform which is fixed in wxWidgets 2.8.12.
