        ////打印内容 为 整个Form
        //Image myFormImage;
        //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
