一、引用BarcodeStandard.dll

        #region BarcodeStandard.dll        /*         *          * 使用说明         需要通过NuGet进行安装BarcodeLib.dll,必不可少         */        string inputString;        /// 
        /// 获取所以打印机驱动名称        /// 
        private void getPrintDocumentlist()        {            PrintDocument print = new PrintDocument();            string sDefault = print.PrinterSettings.PrinterName;//默认打印机名            comboBox_drive.Items.Add(sDefault);            comboBox_drive.Text = sDefault;//显示默认驱动名称            foreach (string sPrint in PrinterSettings.InstalledPrinters)//获取所有打印机名称            {                if (sPrint != sDefault)                {                    comboBox_drive.Items.Add(sPrint);                }            }        }        ///

        ///         ///         private void printDocument1_PrintPage(object sender, PrintPageEventArgs e)        {            Font titleFont = new Font("宋体", 9, FontStyle.Bold);//标题字体                       Font fntTxt = new Font("宋体", 9, FontStyle.Regular);//正文文字                       Brush brush = new SolidBrush(Color.Black);//画刷                       Pen pen = new Pen(Color.Black); //线条颜色                       Point po = new Point(10, 10);            try            {                //画String                e.Graphics.DrawString(GetPrintSW().ToString(), titleFont, brush, po);//打印内容                                             //画横线                //Point[] point = { new Point(20, 50), new Point(200, 50) };//纵坐标不变                //e.Graphics.DrawLines(pen, point);                //画竖线                //Point[] points1 = { new Point(60, 70), new Point(60, 70 + 40) };//横坐标不变                //e.Graphics.DrawLines(pen, points1);                //画矩形                //e.Graphics.DrawRectangle(pen, 20, 70, 90, 90);            }            catch (Exception ex)            {                MessageBox.Show(this, "打印出错！", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);            }        }       ///

二、引用Seagull.BarTender.Print.dll

        #region   Seagull.BarTender.Print.dll        ///

三、引用 Interop.LabelManager2.dll

        #region  Interop.LabelManager2.dll        /// 
        /// 打印功能 CodeSoft        ///
