然后再拖拽一个Button按钮，双击进入其点击事件中

private void button7_Click(object sender, EventArgs e)
            {
                PrintDialog MyPrintDg = new PrintDialog();
                MyPrintDg.Document = printDocument1;
                if (MyPrintDg.ShowDialog() == DialogResult.OK)
                {
                    try
                    {
                        printDocument1.Print();
                    }
                    catch
                    {   //停止打印
                        printDocument1.PrintController.OnEndPrint(printDocument1, new System.Drawing.Printing.PrintEventArgs());
                    }
                }
            }

找到页面设计器中拖拽的printDocument控件上，右击属性，找到事件列表，然后双击其PrintPage事件

编写如下代码：

private void printDocument1_PrintPage(object sender, PrintPageEventArgs e)
            {
                e.Graphics.DrawImage(pictureBox1.Image, 20, 20);
            }
