PDFPrintTest - C++

This sample illustrates how to print PDF document using currently selected default printer. It is possible to use PDFNet printing functionality in both client and server applications without dependance on any third party components.

/** 
 * The following sample is a simplest C/C++ program used to illustrate how to print 
 * PDF document using currently selected default printer. In this sample, PDF::Print class 
 * is used to send data to the printer. 
 * 
 * Following this function is the more complex way of using PDFDraw directly.
 *
 * 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.
 *  
 * The second example uses PDFDraw send unoptimized rasterized data via the print path. 
 *  
 * 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.
