You can use DocumentViewer to view control that can host paginated FixedDocument content such as an XpsDocument. I will show you a sample of using DocumentViewer to print pdf:

Here is the cs code:

 public MainWindow()
        {
            InitializeComponent();
            LoadDocumentViewer("E:\\WPF case\\0622\\pdf\\temp.xps", docViewer);

        }

        static XpsDocument xpsPackage = null;
        public static void LoadDocumentViewer(string xpsFileName, DocumentViewer viewer)
        {
            XpsDocument oldXpsPackage = xpsPackage;
            xpsPackage = new XpsDocument(xpsFileName, FileAccess.Read, CompressionOption.NotCompressed);

            FixedDocumentSequence fixedDocumentSequence = xpsPackage.GetFixedDocumentSequence();
            viewer.Document = fixedDocumentSequence as IDocumentPaginatorSource;

            if (oldXpsPackage != null)
                oldXpsPackage.Close();
            xpsPackage.Close();
        }

Add a DocumentViewer in the xaml:

    <DocumentViewer Name="docViewer"></DocumentViewer>
