xaml文件里：

//定义图片和文本打印变量  
PrintDocument printImage;

public BeginControlChart 方法里：

//图片打印对象 
printImage = new PrintDocument();
 //图片打印事件处理  
printImage.PrintPage += new EventHandler<PrintPageEventArgs>(printImage_PrintPage);

/// <summary>
        /// 打印
        /// </summary>
        private void btnPrint_Click(object sender, RoutedEventArgs e)
        {
            //启动打印图片，出现打印对话框 
            printImage.Print(sTNameClick);
        }

//确认打印后开始打印 
        private void printImage_PrintPage(object sender, PrintPageEventArgs e)
        {
            //确认打印,打印对象 
            e.PageVisual = this.gridVisifire;
