打印 FlowDocument 时避免多列
我正在编写从 FlowDocument 打印的代码。
PrintDialog printDialog = new PrintDialog();
bool? result = printDialog.ShowDialog();
if (result == true)
{
FlowDocument fd = new FlowDocument();
fd.Blocks.Add(new Paragraph(new Run(String.Format("Message:\r\n{0}\r\n", txtMessage.Text))));
fd.PageHeight = printDialog.PrintableAreaHeight;
fd.PageWidth = printDialog.PrintableAreaWidth;
printDialog.PrintDocument((fd as IDocumentPaginatorSource).DocumentPaginator, "print test");
}
此代码将在一页上打印多列。如何避免这种情况？
I am writing code to print from a FlowDocument.
PrintDialog printDialog = new PrintDialog();
bool? result = printDialog.ShowDialog();
if (result == true)
{
FlowDocument fd = new FlowDocument();
fd.Blocks.Add(new Paragraph(new Run(String.Format("Message:\r\n{0}\r\n", txtMessage.Text))));
fd.PageHeight = printDialog.PrintableAreaHeight;
fd.PageWidth = printDialog.PrintableAreaWidth;
printDialog.PrintDocument((fd as IDocumentPaginatorSource).DocumentPaginator, "print test");
}
This code will print multiple columns in one page. How to avoid this?

如果不涉及 printDialog（例如编写 XML 文件），这个解决方案对我有用：
In case, there is no printDialog involved (e.g. Writing a XML-File), this solution worked for me:
