调用BarTender打印标签

        private BarTender.Application btAPP;
        private BarTender.Format btFormat;
        //初始化对象
        btAPP = new BarTender.Application();

                try
                {
                    btFormat = btApp.Formats.Open(AppDomain.CurrentDomain.BaseDirectory + "labCloth1.btw", false, "");

                    //向bartender模板传递变量,SN为条形码数据的一个共享名称
                    btFormat.SetNamedSubStringValue("SN", sn_string);
                    btFormat.SetNamedSubStringValue("NUM", DateTime.Now.Minute.ToString());
                    btFormat.SetNamedSubStringValue("LEN", 50.24.ToString());

                    //选择打印机
                    btFormat.Printer = InitprinterComboBox.Text;

                    //设置打印份数
                    int CopiesOfLabel = Int32.Parse(this.PrintLabNum.Text.ToString());
                    btFormat.IdenticalCopiesOfLabel = CopiesOfLabel;

                    //设置打印时是否跳出打印属性
                    btFormat.PrintOut(false, false);

                    //退出时是否保存标签
                    btFormat.Close(BarTender.BtSaveOptions.btSaveChanges);
                }
                catch (Exception ex)
                {
                    MessageBox.Show("错误信息: " + ex.Message);
                    return;
                }
//
btAPP.Quit(BarTender.BtSaveOptions.btSaveChanges);//界面退出时同步退出bartender进程
