// 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.

func main(){
    // Relative path to the folder containing the test files.
    inputPath := "../../TestFiles/"
    doc := NewPDFDoc(inputPath + "tiger.pdf")
    // Set our PrinterMode options
    printerMode := NewPrinterMode()
    printerMode.SetDPI(100); // regardless of ordering, an explicit DPI setting overrides the OutputQuality setting
    // If the XPS print path is being used, then the printer spooler file will
    // ignore the grayscale option and be in full color
    // printerMode.SetNUp(2,1)
    // printerMode.SetScaleType(PrinterModeE_ScaleType_FitToOutPage)
    // Print the PDF document to the default printer, using "tiger.pdf" as the document
    // name, send the file to the printer not to an output file, print all pages, set the printerMode
    // and a cancel flag to true
    pageSet := NewPageSet(1, doc.GetPageCount())
    boolValue := true
    PrintStartPrintJob(doc, "", doc.GetFileName(), "", pageSet, printerMode, &boolValue)
