ppt.LoadFromFile("Sample.pptx");
//use PrinterSettings object to print presentation slides
PrinterSettings ps = new PrinterSettings();
ps.PrintRange = PrintRange.AllPages;
ps.PrintToFile = true;
ps.PrintFileName = ("Print.xps");
//print the slide with frame
ppt.SlideFrameForPrint = true;
//print the slide with Grayscale
ppt.GrayLevelForPrint = true;
//Print 4 slides horizontal
ppt.SlideCountPerPageForPrint = PageSlideCount.Four;
ppt.OrderForPrint = Order.Horizontal;
////only select some slides to print
//ppt.SelectSlidesForPrint("1", "3");
//print the document
ppt.Print(ps);
}
Code Snippets of set print document name by using PrintDocument object to print presentation slides:
static void Main(string[] args)
{
//load the sample document from file
Presentation ppt = new Presentation();
ppt.LoadFromFile("Sample.pptx");
//use PrintDocument object to print presentation slides
PresentationPrintDocument document = new PresentationPrintDocument(ppt);
//print document to virtual printer
document.PrinterSettings.PrinterName = "Microsoft XPS Document Writer";
//print the slide with frame
ppt.SlideFrameForPrint = true;
//print 4 slides horizontal
ppt.SlideCountPerPageForPrint = PageSlideCount.Four;
ppt.OrderForPrint = Order.Horizontal;
//print the slide with Grayscale
ppt.GrayLevelForPrint = true;
//set the print document name
document.DocumentName = "Print Task";
document.PrinterSettings.PrintToFile = true;
