Print PDF in WPF application

The following code snippet also work with Aspose.PDF.Drawing library.

Direct print

The Aspose.PDF library has the ability to convert PDF files to XPS. We can use this function to organize the printing of documents. Let’s consider the example for direct printing:

.NET Core 3.1

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET

private static void DirectPrintWpf()
{
    // Select a PDF document to print
    var openFileDialog = new OpenFileDialog
    {
        Filter = "PDF Documents|*.pdf"
    };

    if (openFileDialog.ShowDialog() == true)
    {
        // Open the document
        using (var document = new Aspose.Pdf.Document(openFileDialog.FileName))
        {
            using (var memoryStream = new MemoryStream())
            {
                // Convert the document to the XPS format
                document.Save(memoryStream, SaveFormat.Xps);
        
                // Create an XPS package
                using (var package = Package.Open(memoryStream))
                {
                    //Create URI for the XPS package
                    //Any Uri will actually be fine here. It acts as a placeholder for the
                    //Uri of the package inside the PackageStore
                    var inMemoryPackageName = $"memorystream://{Guid.NewGuid()}.xps";
                    var packageUri = new Uri(inMemoryPackageName);
        
                    //Add the package to PackageStore
                    PackageStore.AddPackage(packageUri, package);
        
                    // Open the XPS document from the package
                    using (var xpsDoc = new XpsDocument(package, CompressionOption.Maximum, inMemoryPackageName))
                    {
                        // Get the root document sequence
                        var fixedDocumentSequence = xpsDoc.GetFixedDocumentSequence();
        
                        // Open a print dialog to set printing options
                        var printDialog = new PrintDialog();
                        if (printDialog.ShowDialog() == true)
                        {
                            if (fixedDocumentSequence != null)
                            {
                                // Print converted document
                                printDialog.PrintDocument(fixedDocumentSequence.DocumentPaginator,
                                    "A fixed document");
                            }
                        }
        
                        // Remove the package from the store and close the document after the print
                        PackageStore.RemovePackage(packageUri);
                    }
                }
            }
        }
    }
}

.NET 8

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET

private static void DirectPrintWpf()
{
    // Select a PDF document to print
    var openFileDialog = new OpenFileDialog
    {
        Filter = "PDF Documents|*.pdf"
    };

    if (openFileDialog.ShowDialog())
    {
        // Open the document
        using var document = new Aspose.Pdf.Document(openFileDialog.FileName);
        
        // Convert the document to the XPS format
        using var memoryStream = new MemoryStream();
        document.Save(memoryStream, SaveFormat.Xps);
        
        // Create an XPS package
        using var package = Package.Open(memoryStream);
        
        //Create URI for the XPS package
        //Any Uri will actually be fine here. It acts as a placeholder for the
        //Uri of the package inside the PackageStore
        var inMemoryPackageName = $"memorystream://{Guid.NewGuid()}.xps";
        var packageUri = new Uri(inMemoryPackageName);
        
        //Add the package to PackageStore
        PackageStore.AddPackage(packageUri, package);
        
        // Open the XPS document from the package
        using var xpsDoc = new XpsDocument(package, CompressionOption.Maximum, inMemoryPackageName);
        
        // Get the root document sequence
        var fixedDocumentSequence = xpsDoc.GetFixedDocumentSequence();
        
        // Open a print dialog to set printing options
        var printDialog = new PrintDialog();
        if (printDialog.ShowDialog() == true)
        {
            if (fixedDocumentSequence != null)
            {
                // Print converted document
                printDialog.PrintDocument(fixedDocumentSequence.DocumentPaginator,
                    "A fixed document");
            }
        }
        
        // Remove the package from the store and close the document after the print
        PackageStore.RemovePackage(packageUri);
    }
}

In this case, we will follow these steps:

1. Open PDF file using OpenFileDialog.
2. Convert PDF to XPS and store it in MemoryStream object.
3. Associate MemoryStream object with Xps Package.
4. Add the package to the Package Store.
5. Create an XpsDocument based on package.
6. Get an instance of the FixedDocumentSequence.
7. Send this sequence to the printer using PrintDialog.

View and print document

In many cases, users want to see the document before printing. To implement a view, we can use a DocumentViewer control. Most of the steps for implementing this approach are similar to the previous example.

.NET Core 3.1

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET

private static void PreviewDocumentWithDocumentViewer(DocumentViewer docViewer)
{
    // Select a PDF document to print
    var openFileDialog = new OpenFileDialog
    {
        Filter = "PDF Documents|*.pdf"
    };

    if (openFileDialog.ShowDialog() == true)
    {
        // Open the document
        using (var document = new Aspose.Pdf.Document(openFileDialog.FileName))
        {
            using (var memoryStream = new MemoryStream())
            {
                // Convert the document to the XPS format
                document.Save(memoryStream, SaveFormat.Xps);

                // Create an XPS package
                using (var package = Package.Open(memoryStream))
                {
                    //Create URI for the XPS package
                    var inMemoryPackageName = $"memorystream://{Guid.NewGuid()}.xps";
                    var packageUri = new Uri(inMemoryPackageName);

                    //Add package to PackageStore
                    PackageStore.AddPackage(packageUri, package);

                    // Open the XPS document from the package
                    using (var xpsDoc = new XpsDocument(package, CompressionOption.Maximum, inMemoryPackageName))
                    {
                        // Display the document in the DocumentViewer
                        docViewer.Document = xpsDoc.GetFixedDocumentSequence();
                    }
                }
            }
        }
    }
}

.NET 8

// For complete examples and data files, visit https://github.com/aspose-pdf/Aspose.PDF-for-.NET

private static void PreviewDocumentWithDocumentViewer(DocumentViewer docViewer)
{
    // Select a PDF document to print
    var openFileDialog = new OpenFileDialog
    {
        Filter = "PDF Documents|*.pdf"
    };

    if (openFileDialog.ShowDialog() == true)
    {
        // Open the document
        using var document = new Aspose.Pdf.Document(openFileDialog.FileName);

        // Convert the document to the XPS format
        using var memoryStream = new MemoryStream();
        document.Save(memoryStream, SaveFormat.Xps);

        // Create an XPS package
        using var package = Package.Open(memoryStream);

        //Create URI for the XPS package
        var inMemoryPackageName = $"memorystream://{Guid.NewGuid()}.xps";
        var packageUri = new Uri(inMemoryPackageName);

        //Add package to PackageStore
        PackageStore.AddPackage(packageUri, package);

        // Open the XPS document from the package
        using var xpsDoc = new XpsDocument(package, CompressionOption.Maximum, inMemoryPackageName);

        // Display the document in the DocumentViewer
        docViewer.Document = xpsDoc.GetFixedDocumentSequence();
    }
}
