代码：Dispatcher.Invoke可以防止报错：调用线程必须为 STA，因为许多 UI 组件都需要。

public void PrintIt()
{
WaybillData waybill = new WaybillData();//TODO:自己构造数据
System.Windows.Application.Current.Dispatcher.Invoke(System.Windows.Threading.DispatcherPriority.Normal, new Action<WaybillData>(PrintAction), waybill);
}
public void PrintAction(WaybillData t)
        {
            PrintDialog pdlg = new PrintDialog();
            FlowDocument doc = PrintPreviewWindow.LoadDocumentAndRender("JDFlowDocument.xaml", t);
            Dispatcher.Invoke(new DoPrintMethod(DoPrint), DispatcherPriority.ApplicationIdle, pdlg, ((IDocumentPaginatorSource)doc).DocumentPaginator);
        }
 private delegate void DoPrintMethod(PrintDialog pdlg, DocumentPaginator paginator);
        private void DoPrint(PrintDialog pdlg, DocumentPaginator paginator)
        {
            pdlg.PrintDocument(paginator, "JDFlowDocument");
        }
