如何成批打印多个流程文档?

var printDialog = new PrintDialog();
if(printDialog.ShowDialog() == true) {      
  var xpsDocumentWriter = PrintQueue.CreateXpsDocumentWriter(printDialog.PrintQueue);

  foreach(var person in persons) {
    var doc = Application.LoadComponent(new Uri("Template.xaml", UriKind.Relative)) as FlowDocument;
      doc.DataContext = persons;
      var paginator = ((IDocumentPaginatorSource)doc).DocumentPaginator;          
      xpsDocumentWriter.Write(paginator);
    }
  }

这些都是线程问题。分配 DataContext 确保线程处理其等待队列:

Dispatcher.CurrentDispatcher.Invoke(
        DispatcherPriority.SystemIdle, new DispatcherOperationCallback(_ => null), null);
