具有横向和纵向页面的PrintDialog

I have a System.Window.Controls.PrintDialog and I want to print pages with landscape mode and portrait mode in with single PrintTicket but it seems I only can set the orientation once.

我有一个System.Window.Controls.PrintDialog，我想用单个PrintTicket打印横向模式和纵向模式的页面，但似乎我只能设置一次方向。

As long as I want to print on paper this may not be a big deal but I want to print/create a PDF document from my Printjob. There I need pages with Landscape and Portrait mode in onc document.

只要我想在纸上打印，这可能不是什么大问题，但我想从我的Printjob打印/创建PDF文档。我需要在onc文档中使用横向和纵向模式的页面。

So far I managed to rotate the landscape pages 90 degree and this works fine but in the PrintPreview it looks very strange because of the rotated content.

到目前为止，我设法将景观页面旋转90度，这很好，但在PrintPreview中，由于旋转的内容，它看起来很奇怪。

Not as clean as you would like and more of a workaround but I think it might accomplish your goal. You can use the iTextSharp library to concatenate PDFs into one following multiple print jobs. Here is some sample code.

不像你想要的那么干净，而是更多的解决方法，但我认为它可能会实现你的目标。您可以使用iTextSharp库将PDF连接到多个打印作业之后。这是一些示例代码。

Hopefully someone comes up with a more straight forward solution.

希望有人提出更直接的解决方案。

A long time later ...

很久以后......

You can do this by providing an EventHandler that gets called, asking for a custom PrintTicket, before each page is printed. The PageViewModel here effectively comprises

您可以通过在每个页面打印之前提供一个被调用的EventHandler，要求自定义PrintTicket来完成此操作。这里的PageViewModel有效地包含

PageViewModel{
    Page Page {get;set;}
    PageOrientation? PageOrientation {get;set}
}

if (PrintDialog.ShowDialog() == true)
  {
    XpsDocumentWriter xpsDocumentWriter = PrintQueue.CreateXpsDocumentWriter(PrintDialog.PrintQueue);
    xpsDocumentWriter.WritingPrintTicketRequired += (s, e) =>
    {
      PageViewModel pVM = publicationVM.Pages[e.Sequence - 1];
      if (pVM.Orientation != null && pVM.Orientation != publicationVM.Orientation)
      {
        e.CurrentPrintTicket = new PrintTicket();
        e.CurrentPrintTicket.PageOrientation = PageOrientation.Portrait;
      }
    };
    VisualsToXpsDocument visualsToXpsDocument = (VisualsToXpsDocument) xpsDocumentWriter.CreateVisualsCollator(PrintDialog.PrintTicket, PrintDialog.PrintTicket);
    visualsToXpsDocument.BeginBatchWrite();
    Page page;
    foreach (PageViewModel pVM in publicationVM.Pages)
    {
      page = pVM.Page;
      visualsToXpsDocument.Write(page);
    }
    visualsToXpsDocument.EndBatchWrite();
  }

and bingo! mixed Portrait and Landscape. Duplexing this is fine too.

和宾果游戏！混合肖像和风景。双工这也很好。
