I had an idea to make things simpler to code and keep them reasonably 
simple for users.
My first goal is to hide wxPrintout that makes things rather complicated.

We could create a printing class with a Print() method to start printing 
and a virtual PrintPage() method to be implemented by descendant classes.
When printing this class could create a wxPrintout and the 
wxPrintout::PrintPage() function could call the same function in the new 
class.

The user's code is almost surely inside a class: just derive the user's 
class from the printing class, add the PrintPage() implementation and 
call the Print() method.

This is just a quick explanation: feel free to ask for mere details.

Do you think that this could be a good idea?
