*
* Example program to demonstrate printing using the Win32 API/GDI.
* I'm new to printing with the Win32 GDI myself (although I've
* used the GDI heaps before for gfx etc.) - I've been
* trying for a long time to find useful info on the Internet
* about this very thing, but came across next to nothing.
* I thought it'd be a disservice to the Internet not to get
* something about printing with Win32/GDI out the door ASAP!
