When you need to print many PDF documents, surely you don't want to see the print dialog every time. This article will show you clearly how to print PDF documents in WPF without invoking Print Dialog by using Spire.PDFViewer for WPF.

Here comes to the steps of how to print PDF files in WPF.

Step 1: First you need to create a new project by choosing "WPF Application".

Step 2: Set the Target Framework to be .NET Framework 4 in Properties.

Step 3: Right-click on the blank part of the Toolbox → "Add Tab" → "Choose Items" → "WPF Components" → "Browse" to the "Bin" folder → find the file "Spire.PdfViewer.Wpf.dll" → "OK".

Step4: Spire.PDFViewer offers PdfViewer and PdfDocumentViewer to print the PDF files in C#. Please check the code snippet as below:

Print via PdfViewer without invoking PrintDialog with the following method.

PrintDialog dialog = new PrintDialog();
this.pdfViewer1.PrintDialog = dialog;
dialog.PrintDocument(pdfViewer1.PrintDocument.DocumentPaginator, "Print Document");

Print via PdfDocumentViewer without invoking PrintDialog with the following method.

PrintDialog dialog = new PrintDialog();
this.pdfDocumentViewer1.PrintDialog = dialog;
dialog.PrintDocument(pdfDocumentViewer1.PrintDocument.DocumentPaginator, "Print Document");

Then your PDF document will be printed directly without showing the print dialog.

Full codes of how to print PDF file in WPF.

namespace PrintPDFinWPF
{
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            this.pdfViewer1.LoadFromFile("sample.pdf");
            ////Print the PDF file directly with PrintDialog
            //this.pdfViewer1.Print();

            //Print without Print Dialog
            PrintDialog dialog = new PrintDialog();
            this.pdfViewer1.PrintDialog = dialog;
            dialog.PrintDocument(pdfViewer1.PrintDocument.DocumentPaginator, "Print Document");
        }
    }
}

Background

PDF is now widely used to represent document in independent specification. It encapsulates a complete description of a fixed-layout flat document, including the text, fonts and graphics and so on. Due to its powerful functions, it is difficult for developers to parse its format. Or more specifically, to parse content out from PDF document and convert it to different image format is a tough task for some developers. This article will help you solve this problem by using PDF document viewer component Spire.PDFViewer for WPF by 5 easy steps. Firstly, you can download Spire.PDFViewer for WPF.

Target

To convert a specified or random page including frames of images from PDF file to TIFF programmatically.

Step 1: To create WPF application in Visual Studio and reference Spire.PdfViewer.WPF dlls.

Set .NET 4 as target framework

Step 2: Instance an object of Spire.PdfViewer.Wpf.PdfDocumentViewer

PdfDocumentViewer pdfViewer = new PdfDocumentViewer();

Step 3: Call the “LoadFromFile”of PdfDocumentViewer object and load a PDF file.

pdfViewer.LoadFromFile ("sample.pdf");

Step 4: Create an array and save all pages of this PDF file.

int[] pageNumbers=new int[pageCount];
            for (int i=0;i

Step 5: Save it to Tiff image format

pdfViewer.SaveAsImage("sample.tiff",pageNumbers);

The following code snippet shows all the code when converting pdf page to tiff image:

private void Button_Click(object sender, RoutedEventArgs e)
        {
            // Instance an object of Spire.PdfViewer.Wpf.PdfDocumentViewer
            PdfDocumentViewer pdfViewer = new PdfDocumentViewer();
            //Load a pdf file 
            pdfViewer.LoadFromFile("sample.pdf");
            int pageCount = pdfViewer.PageCount;
            // create an array and save all pages of this PDF file.
            int[] pageNumbers=new int[pageCount];
            for (int i=0;i

Spire.PDFViewer for WPF is a powerful WPF PDF Viewer control which enables developers to display PDF documents with their WPF applications without Adobe Reader. It’s available to load and view PDF documents like PDF/A-1B, PDF/X1A, and even encrypted from stream, file and byte array with support for printing, zooming, etc.

In people's daily life, we can open a PDF document by right clicking the open option as well as using C#, VB.NET or other programming languages. Both methods are available as long as you have a PDF Document, but for PDF itself, it has no viewing function, thus, we need to use PDF Viewer to help us view it. This article is designed to open a PDF Document with C#, VB.NET via PDF Viewer by two methods.

Spire. PDFViewer is designed for viewing PDF files from .NET application. It does NOT require Adobe Read or any other 3rd party software/library installed on system. By using Spire.PDFViewer, we can do this job easily. Please just follow the below procedure.

Step 1: Create a new project

• Freely Download Spire.PDFViewer
• Create a new project in Visual Studio and add a toolScript in Form1
• Set its target Framework to be .NET Framework 4
• Add Spire.PdfViewer. Forms as reference in Project. And add using at the top of the method. Please see below:

using System.IO; 
using Spire.PdfViewer.Forms;

Imports Sytem. IO
Imports Spire.PdfViewer.Forms

Step 2: Open a PDF Document with C#, VB.NET via Spire.PDFViewer

Method one: This method is to directly load a PDF file from system, then open it.

        public partial class Form1 : Form
    {
       
        public Form1()
        {
            InitializeComponent();
            
        }

        private void Form1_Load(object sender, EventArgs e)
        {
         
        }

        private void toolStripButton1_Click(object sender, EventArgs e)
        {
            string pdfDoc = @"D:\michelle\e-iceblue\Spire.Office.pdf";
            if (File.Exists(pdfDoc))
            {
                this.pdfDocumentViewer1.LoadFromFile(pdfDoc);
            }

        }
    }
 }

Public Partial Class Form1
		Inherits Form

		Public Sub New()

			InitializeComponent()
		End Sub

		Private Sub Form1_Load(sender As Object, e As EventArgs)

		End Sub

		Private Sub toolStripButton1_Click(sender As Object, e As EventArgs)
			Dim pdfDoc As String = "D:\michelle\e-iceblue\Spire.Office.pdf"
			If File.Exists(pdfDoc) Then
				Me.pdfDocumentViewer1.LoadFromFile(pdfDoc)
			End If

		End Sub
	End Class
End Namespace

Method Two: This method allows you to choose the PDF file you want to open in a dialog box from your computer.

public partial class Form1 : Form
 {
       
        public Form1()
        {
            InitializeComponent();
            
        }

        private void Form1_Load(object sender, EventArgs e)
        {
         
        }

        private void toolStripButton1_Click(object sender, EventArgs e)
        {
            OpenFileDialog dialog = new OpenFileDialog();
            dialog.Filter = "PDF document (*.pdf)|*.pdf";
            DialogResult result = dialog.ShowDialog();
            if (result == DialogResult.OK)
            {
                try
                {
                    string pdfFile = dialog.FileName;
                    this.pdfDocumentViewer1.LoadFromFile(pdfFile);
                }
                catch (Exception exe)
                {
                    MessageBox.Show(exe.Message, "Spire.PdfViewer Demo", MessageBoxButtons.OK, MessageBoxIcon.Error);
                }

            }

        }
   }

Public Partial Class Form1
	Inherits Form

	Public Sub New()

		InitializeComponent()
	End Sub

	Private Sub Form1_Load(sender As Object, e As EventArgs)

	End Sub

	Private Sub toolStripButton1_Click(sender As Object, e As EventArgs)
		Dim dialog As New OpenFileDialog()
		dialog.Filter = "PDF document (*.pdf)|*.pdf"
		Dim result As DialogResult = dialog.ShowDialog()
		If result = DialogResult.OK Then
			Try
				Dim pdfFile As String = dialog.FileName
				Me.pdfDocumentViewer1.LoadFromFile(pdfFile)
			Catch exe As Exception
				MessageBox.Show(exe.Message, "Spire.PdfViewer Demo", MessageBoxButtons.OK, MessageBoxIcon.[Error])

			End Try
		End If

	End Sub
End Class

Step 3: Launch the file

Press F5, you can see Form1 display itself as picture below:

Then click "open" in the Form. When you use method one, you can see the PDF document content shows in the Form1. Also you can set the size of the form according to your own preference. When you use method two, you can choose the PDF Document by yourself in a dialog box. And then preview it in Form1.

Note: I set the default name of toolScript to be "open".
