n PDF Viewer, How to Directly print the PDF File without selection of Printer (Directly Print as per printer name set by code) 

We can directly print PDF document by setting the printer name through code level. Please find the below code snippet to print the document through PdfViewerControl. 
 




PdfViewerControl pdfViewerControl = new PdfViewerControl(); 
pdfViewerControl.Load(@"..\..\Data\Barcode.pdf"); 
pdfViewerControl.PrintDocument.PrinterSettings.PrinterName = "Microsoft XPS Document Writer"; 
pdfViewerControl.Print(false); 
We can also set the printer name in code level through PrintDialog class while silent printing the document. Please find the KB link from below.https://www.syncfusion.com/kb/4625/how-to-silent-print-a-pdf-document-to-a-specified-printer 
 


How to get the Direct Print Button Click Event in PDFViewer, so that PDF can directly print as per the printer name set by coding. 

We can use the ‘ButtonClicked’ event of PdfViewerControl, to set the printer name while printing the document. The ‘ButtonClicked’ event is triggered when we click the buttons in the PdfViewerControl’s toolbar.  
Please find the below code snippet to trigger the ButtonClicked event. 
 




pdfViewerControl.ButtonClicked += PdfViewerControl_ButtonClicked; 
 
private void PdfViewerControl_ButtonClicked(object sender, ButtonClickedEventArgs e) 
        { 
            if (e.ButtonName == "Print") 
            { 
                e.CancelDefaultAction = true; 
               pdfViewerControl.PrintDocument.PrinterSettings.PrinterName = "Microsoft XPS Document Writer"; 
                pdfViewerControl.Print(false); 
            } 
        }

Is there a way to know if the Print is success or fail or user cancelled or what exactly happend to log?

In WPF PdfViewer, The EndPrint event is triggered when the last page of the document has been printed. However, it is also triggered if the printing process is canceled or if an exception occurs during the process.
