	// The following sample illustrates how to convert to PDF with virtual printer on Windows.
	// It supports several input formats like docx, xlsx, rtf, txt, html, pub, emf, etc. For more details, visit 
	// https://docs.apryse.com/documentation/windows/guides/features/conversion/convert-other/
	// 
	// To check if ToPDF (or ToXPS) require that PDFNet printer is installed use Convert::RequiresPrinter(filename). 
	// The installing application must be run as administrator. The manifest for this sample 
	// specifies appropriate the UAC elevation.
	//
	// Note: the PDFNet printer is a virtual XPS printer supported on Vista SP1 and Windows 7, or .NET Framework
	// 3.x or higher. For older versions of .NET Framework running on Windows XP or Vista SP0 you need to install 
	// the XPS Essentials Pack (or equivalent redistributables). 
	//
	// Also note that conversion under ASP.NET can be tricky to configure. Please see the following document for advice: 
	// http://www.pdftron.com/pdfnet/faq_files/Converting_Documents_in_Windows_Service_or_ASP.NET_Application_using_PDFNet.pdf
