/// The following sample illustrates how to print PDF document using currently selected
/// default printer. 
/// 
/// The first example uses the new PDF::Print::StartPrintJob function to send a rasterization 
/// of the document with optimal compression to the printer.  If the OS is Windows 7, then the
/// XPS print path will be used to preserve vector quality.  For earlier Windows versions
/// the GDI print path will be used.  On other operating systems this will be a no-op
/// 
/// The second example uses PDFDraw send unoptimized rasterized data via awt.print API. 
/// 
/// If you would like to rasterize page at high resolutions (e.g. more than 600 DPI), you 
/// should use PDFRasterizer or PDFNet vector output instead of PDFDraw.
