此代码将只打印一页，但控件的高度超过了页面高度，因此需要在第二页上打印。我一直在调查什么将使控件能够进入另一个页面。我到了 DocumentPaginator 并调整了大小，使其比 sz 变量更大或更小，但没有区别。关于什么控制新页面的创建的任何想法？大小与分页有关吗？
private void Print()
{
var pd = new PrintDialog();
var document = new FixedDocument();
var fixedPage = new FixedPage();
var pageContent = new PageContent();
System.Printing.PrintCapabilities capabilities = pd.PrintQueue.GetPrintCapabilities(pd.PrintTicket);
System.Windows.Size sz = new System.Windows.Size(capabilities.PageImageableArea.ExtentWidth, capabilities.PageImageableArea.ExtentHeight);
MarSheetReport mar = new MarSheetReport();
document.DocumentPaginator.PageSize = sz;
Transform originalScale = fixedPage.LayoutTransform;
//get selected printer capabilities
fixedPage.LayoutTransform = new ScaleTransform(0.2823293807641634 + 0.2498215560314061, 0.2823293807641634 + 0.2498215560314061);
fixedPage.Width = sz.Width;
fixedPage.Height = sz.Height;
// Add visual, measure/arrange page.
fixedPage.Children.Add(mar.o);
fixedPage.Measure(sz);
fixedPage.Arrange(new System.Windows.Rect(new System.Windows.Point(capabilities.PageImageableArea.OriginWidth, capabilities.PageImageableArea.OriginHeight), sz));
fixedPage.UpdateLayout();
//fixedPage.LayoutTransform = originalScale;
((IAddChild)pageContent).AddChild(fixedPage);
document.Pages.Add(pageContent);
pd.PrintDocument(document.DocumentPaginator, "My Document");
}
