            //myFormImage = new Bitmap(this.Width, this.Height);
            //Graphics g = Graphics.FromImage(myFormImage);
            //g.CopyFromScreen(this.Location.X, this.Location.Y, 0, 0, this.Size);
            //e.Graphics.DrawImage(myFormImage, 0, 0);

            ////打印内容 为 局部的 this.groupBox1
            //Bitmap _NewBitmap = new Bitmap(groupBox1.Width, groupBox1.Height);
            //groupBox1.DrawToBitmap(_NewBitmap, new Rectangle(0, 0, _NewBitmap.Width, _NewBitmap.Height));
            //e.Graphics.DrawImage(_NewBitmap, 0, 0, _NewBitmap.Width, _NewBitmap.Height);

            Graphics g = e.Graphics;   //先建立画布   
            int x = 80;
