PdfDocumentSource allows you to print a PDF file. It provides support for printing through the Print method of the C1DocumentSource abstract class. The Print method has two overloads, Print (PrinterSettings printerSettings) and Print (C1PrintOptions options). You can add the Print method using C1PdfDocumentSource to print a PDF without the need of a viewer. Following code explains how the method can be used. The code in the topic uses Print (C1PrintOptions options) method for printing a PDF file.

To print PDF

1. Add a button control to the design view for exporting PDF.
2. Add the following namespace in the code view.
   • Visual Basic
   • C#

   • Visual Basic

   Imports C1.WPF.Document
   

   • C#

   using C1.WPF.Document;
   

3. Add a PDF file to the project. In our case, we have used PDF file named DefaultDocument.pdf from the product sample.
4. Initialize the instances of C1PdfDocumentSource and PrintDialog class using the following code:
   • Visual Basic
   • C#

   • Visual Basic

   Dim pds As New C1PdfDocumentSource()
   Dim pdialog As New PrintDialog()
   

   • C#

   C1PdfDocumentSource pds = new C1PdfDocumentSource();
   PrintDialog pdialog = new PrintDialog();
   

5. Load the PDf file into the object of C1PdfDocumentSource using LoadFromFile method:
   • Visual Basic
   • C#

   • Visual Basic

   pds.LoadFromFile("..\..\DefaultDocument.pdf")
   

   • C#

   pds.LoadFromFile(@"..\..\DefaultDocument.pdf");
   

6. Add the following code to the button's click event to print the PDF file using Print method.
   
   • Visual Basic
   • C#

   • Visual Basic

   pdialog.MaxPage = CUInt(pds.PageCount)
   Dim dr As System.Nullable(Of Boolean) = pdialog.ShowDialog()
   
   Try
      Dim po = New C1PrintOptions()
      po.PrintQueue = pdialog.PrintQueue
      po.PrintTicket = pdialog.PrintTicket
      If pdialog.PageRangeSelection = PageRangeSelection.UserPages Then
           po.OutputRange = New OutputRange(pdialog.PageRange.PageFrom, _
                                            pdialog.PageRange.PageTo)
      End If
   
      'Print PDF
      pds.Print(po)
      MessageBox.Show(Me, "Document was successfully printed.", _
                      "Information", MessageBoxButton.OK, _
                      MessageBoxImage.Information)
   Catch ex As Exception
      MessageBox.Show(Me, ex.Message, "Error", MessageBoxButton.OK, _
                      MessageBoxImage.[Error])
   End Try
   

   • C#

   pdialog.MaxPage = (uint)pds.PageCount;
   bool? dr = pdialog.ShowDialog();
   
   try
   {
       var po = new C1PrintOptions();
       po.PrintQueue = pdialog.PrintQueue;
       po.PrintTicket = pdialog.PrintTicket;
       if (pdialog.PageRangeSelection == PageRangeSelection.UserPages)
           po.OutputRange = new OutputRange(pdialog.PageRange.PageFrom,
                                            pdialog.PageRange.PageTo);
   
       //Print PDF
       pds.Print(po);
       MessageBox.Show(this, "Document was successfully printed.",
                       "Information", MessageBoxButton.OK,
                       MessageBoxImage.Information);
   }
   catch (Exception ex)
   {
       MessageBox.Show(this, ex.Message, "Error",
                       MessageBoxButton.OK, MessageBoxImage.Error);
   }
