废话不多说，先上代码：
环境 .net framework 2.0

            }
            catch (Exception ee)
            {
                MessageBox.Show(ee.Message);
            }
        }

        private void button1_Click(object sender, EventArgs e)
        {
            printDocument5.PrinterSettings.PrinterName = "Gprinter GP-3100TU";//打印机名字//如果不指定，就是默认打印机
            barcode_sub01 = "1099009900";
            printDocument5.Print();
        }
    }
}

一共两个控件、button1、printDocument5
