PrintDialog printDiag = new PrintDialog();
printDiag.UserPageRangeEnabled = true;
PrintCapabilities capabilities = printDiag.PrintQueue.GetPrintCapabilities(printDiag.PrintTicket)

double scale = Math.Min(capabilities.PageImageableArea.ExtentWidth / canvasDrawing.ActualWidth
, capabilities.PageImageableArea.ExtentHeight / canvasDrawing.ActualHeight);

Canvas.LayoutTransform = new ScaleTransform(scale, scale);

Size sz = new Size(capabilities.PageImageableArea.ExtentWidth
, capabilities.PageImageableArea.ExtentHeight);

Canvas.Measure(sz);
Canvas.Arrange(new Rect(new Point(capabilities.PageImageableArea.OriginWidth,capabilities.PageImageableArea.OriginHeight), sz));
canvas变形后怎么还原！！！！

不行主要是 canvasDrawing.Arrange(new Rect(new Point(capabilities.PageImageableArea.OriginWidth, capabilities.PageImageableArea.OriginHeight), sz)); 这个怎么还原!

试试这个代码，Sorry!公司无法上Q

ScaleTransform scaleTrans = (ScaleTransform)canvasDrawing.LayoutTransform;

            scaleTrans.ScaleX = 1.0;

            scaleTrans.ScaleY = 1.0;
