Printing PDF Files in WPF Pdf Viewer

PDF Viewer allows printing loaded PDFs using the Print button in the toolbar. The following Print dialog opens upon triggering the Print button.

NOTE

• PdfDocumentView is used to view the PDF documents without the toolbar. So, make use of PdfViewerControl to print the document using Print button in the toolbar.

Silent Printing

The PrintDocument property of PdfViewerControl returns System.Drawing.Printing.PrintDocument that helps to complete printing using PrintDialog. This type of printing can be used when trying to print the PDF document with the custom printer settings. The following code sample demonstrates this:

c#

PrintDialog dialog = new PrintDialog();
dialog.PrintDocument(pdfViewerControl.PrintDocument.DocumentPaginator, "Essential PDF Viewer");

vbnet

Dim dialog As New PrintDialog()
dialog.PrintDocument(pdfViewerControl.PrintDocument.DocumentPaginator, "Essential PDF Viewer")

When you prefer to perform Silent printing with the default printer settings, then using Print method in the PDF Viewer control is the best approach. The following code example illustrates the same.

c#

//Initialize PDF Viewer.

PdfViewerControl pdfViewer1 = new PdfViewerControl();

//Load the PDF.

pdfViewer1.Load("Sample.pdf");

// Printing document using Print method

pdfviewer1.Print();

vbnet

'Initialize PDF Viewer.

Private pdfViewer1 As New PdfViewerControl()

'Load the PDF.

pdfViewer1.Load("Sample.pdf")

' Printing document using Print method

pdfviewer1.Print()

Customizing print size

PDF viewer printer settings allows scaling PDF pages to shrink or enlarge while printing.

Actual Size

Actual size is the default value of print size option in printer settings. This prints the loaded PDF document without any scaling factors. The pages that do not fit on the paper will be cropped. The following code example illustrates how to print the document in Actual Size.

c#

// Prints the document in actual size.

pdfviewer1.PrinterSettings.PageSize = PdfViewerPrintSize.ActualSize;

vbnet

' Prints the document in actual size.

pdfviewer1.PrinterSettings.PageSize = PdfViewerPrintSize.ActualSize

Fit

Fit option enlarges or reduces each page to fit the printable area of the selected paper size. The following code example illustrates the same.

c#

// Prints the document in fit size.

pdfviewer1.PrinterSettings.PageSize = PdfViewerPrintSize.Fit;

vbnet

' Prints the document in fit size.

pdfviewer1.PrinterSettings.PageSize = PdfViewerPrintSize.Fit

Custom Scale

Custom Scale option resizes the page with the specified scale percentage. The following code example illustrates the same.

c#

// Prints the document with custom scaling.

pdfviewer1.PrinterSettings.PageSize = PdfViewerPrintSize.CustomScale;

// Scale percentage with the page to be resized and it is applicable only for Custom Scale. The default value is 100.

pdfviewer1.PrinterSettings.ScalePercentage = 120;

vbnet

' Prints the document with custom scaling.

pdfviewer1.PrinterSettings.PageSize = PdfViewerPrintSize.CustomScale

' Scale percentage with the page to be resized and it is applicable only for Custom Scale. The default value is 100.

pdfviewer1.PrinterSettings.ScalePercentage = 120

Printing PDF document with orientation settings

PDF Viewer printer settings allows the user to print the document with a custom orientation.

Auto Portrait/Landscape

Auto Portrait/Landscape is the default option and it automatically selects the best orientation (Portrait or Landscape) based on the content and selected paper. The following code example illustrates how to print the document in Auto orientation.

c#

// Prints the document in auto orientation.

pdfviewer1.PrinterSettings.PageOrientation = PdfViewerPrintOrientation.Auto;

vbnet

' Prints the document in auto orientation.

pdfviewer1.PrinterSettings.PageOrientation = PdfViewerPrintOrientation.Auto

Portrait

Portrait option prints the PDF document in portrait orientation and it overrides the orientation settings provided in the print dialog. The following code example illustrates the same.

c#

// Prints the document in portrait orientation.

pdfviewer1.PrinterSettings.PageOrientation = PdfViewerPrintOrientation.Portrait;

vbnet

' Prints the document in portrait orientation.

pdfviewer1.PrinterSettings.PageOrientation = PdfViewerPrintOrientation.Portrait

Landscape

Landscape option prints the PDF document in landscape orientation and it overrides the orientation settings provided in print dialog. The following code example illustrates the same.

c#

// Prints the document in landscape orientation.

pdfviewer1.PrinterSettings.PageOrientation = PdfViewerPrintOrientation.Landscape;

vbnet

' Prints the document in landscape orientation.

pdfviewer1.PrinterSettings.PageOrientation = PdfViewerPrintOrientation.Landscape

Set the custom document name to be displayed when printing

PDF viewer allows you to set the custom document name to be displayed when printing the PDF document using the DocumentName property that is available in the PrinterSettings. You can either set the original file name or a custom text to the property for display. Setting the DocumentName property will affect the Document name details in the print status dialog.

The DocumentName property will also affect the Document name details in the print queue information window.

The following code shows how to set the original file name to the DocumentName property.

c#

using System.IO;
using System.Windows;

namespace PdfViewer
{
    /// <summary>
    /// Interaction logic for Window1.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        #region Constructor
        public MainWindow()
        {
            InitializeComponent();

            //Load PDF file with the absolute file path.
            string filePath = Path.GetFullPath(@"../../Data/PDF_Succinctly.pdf");
            pdfViewer.Load(filePath);
            
            //Get the file name
            string fileName = pdfViewer.DocumentInfo.FileName;
            
            //Set the document name to be displayed when printing the document.
            pdfViewer.PrinterSettings.DocumentName = fileName;

            //Print the file.
            pdfViewer.Print();
        }
        #endregion
    }
}

Hide Print Status dialog when printing the PDF files

PDF Viewer allows you to hide the following print status dialog when printing the PDF files by setting the value false to the ShowPrintStatusDialog property that is available in the PrinterSettings.

It will be helpful if no UI interactions are required when printing. The following code shows how to hide the print status dialog using the ShowPrintStatusDialog property.

c#

using System.IO;
using System.Windows;

namespace PdfViewer
{
    /// <summary>
    /// Interaction logic for Window1.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        #region Constructor
        public MainWindow()
        {
            InitializeComponent();

            //Load PDF file.
            string filePath = Path.GetFullPath(@"../../Data/PDF_Succinctly.pdf");
            pdfViewer.Load(filePath);
            
            //Set the document name to be displayed when printing the document.
            pdfViewer.PrinterSettings.ShowPrintStatusDialog = false;

            //Print the file.
            pdfViewer.Print();
        }
        #endregion
    }
}
