打印带注释的 XPS 失败

Question

这个有效

FixedDocumentSeqeunce fixedDocumentSeqeunce = XPSdoc.GetFixedDocumentSeqeunce();    
DocumentPaginator paginator = fixedDocumentSeqeunce.DocumentPaginator;

printDialog.PrintDocument(paginator, "Title");

这失败了

AnnotationDocumentPaginator adp = new AnnotationDocumentPaginator(paginator, service.Store); 
// same paginator as above    
printDialog.PrintDocument(adp, "Title");

printDialog.PrintDocument(adp, "Title");是什么杀死了它
它似乎以某种方式破坏了 XPSdoc

商店看起来不错 - 我可以统计注释数量
即使我创建零注释也会失败
但是打印本身并没有失败——我得到了一个有效的打印
上面的 try catch 没有捕获到错误
打印后几秒钟出现以
开头的错误（我有一个未处理异常的处理程序）

The specified visual is not an ancestor of the Visual

应用程序崩溃并且 XPS 文档永远不会在 DocumentViewer 中重绘

我可以使用 ScrollViewer 获取 FlowDocuments 来打印注释
并以相同的方式创建商店，所以我认为代码很好

.NET 4.5

不知道我的大程序发生了什么，但我现在无法在小程序上重现它

搞清楚
在失败的代码中，我没有使用

FixedDocumentSeqeunce fixedDocumentSeqeunce = XPSdoc.GetFixedDocumentSeqeunce();

在 printDialog.PrintDocument 中，我使用了与控件绑定的完全相同的 fixedDocumentSeqeunce。 Print 必须更改 fixedDocumentSeqeunce，因此它需要一个新的 fixedDocumentSeqeunce。
