在网上参考了其它的资料，研究了bartender打印，走了不少弯路。

安装完bartender后，装全功能版本，在安装路径下，可以找到sdk文件，我需要根据传入的excel文件，检查bartender标签中，有没有指定的列进行打印， barterder10.0版本不支持返回当前标签文件有哪些嵌入式字段，10.1支持，所以只好装了10.1版本，安装了全功能试用版本

引用Seagull.BarTender.Print.dll即可，在安装程序目录下可以找到，调用代码如下

using Seagull.BarTender.Print;using System;using System.Collections.Generic;using System.Data;using System.Diagnostics;using System.Text;namespace libPrintBarTender{    public class CPrinter    {        /// <summary>        ///   dtPrint.Columns.Add("EZPrinter");       // 打印机名字        ///      dtPrint.Columns.Add("EZLabelFile");     // 打印的模板文件        ///      dtPrint.Columns.Add("EZLabelType");     // 打印的类型    Label 标签        ///       dtPrint.Columns.Add("EZLabelCopies");   // 打印的份数        ///       dtPrint.Columns.Add("EZPrintMission");  // 默认值1        /// </summary>        /// <param name="dtPrintInfo"></param>        public void PrintLabel(DataTable dtPrintInfo)        {            Engine engine = null;            LabelFormatDocument btFormat = null;            try            {                if (dtPrintInfo.Rows.Count == 0)                {                    return;                }                engine = new Engine(true);                if (engine == null)                {                    throw new Exception("初始化打印机失败，请检查bartender软件!");                }                string printerName = dtPrintInfo.Rows[0]["EZPrinter"].ToString();                string labelFile = dtPrintInfo.Rows[0]["EZLabelFile"].ToString();                try                {                    btFormat = engine.Documents.Open(labelFile, printerName);                }                catch (Exception ex)                {                    throw new Exception("打开模块与打印机失败:" + ex.Message);                }                // 打印标签                PrintInfo(btFormat, dtPrintInfo);                if (btFormat != null)                {                    btFormat.Close(SaveOptions.DoNotSaveChanges);                }                if (engine != null)                {                    engine.Stop(SaveOptions.DoNotSaveChanges);                }            }            catch (Exception ex)            {                throw new Exception("打印失败:" + ex.Message);            }            finally            {            }        }        private static List<string> GetPrintLabelTemplateFields(LabelFormatDocument btFormat)        {            List<string> colLists = new List<string>(btFormat.SubStrings.Count);            for(int i=0; i< btFormat.SubStrings.Count; i++ )            {                colLists.Add(btFormat.SubStrings[i].Name);            }            return colLists;        }        private static void RemoveMuchFields(LabelFormatDocument btFormat, ref DataTable dtPrintInfo)        {            List<string> colLists = GetPrintLabelTemplateFields(btFormat);            int m = 0;            while (dtPrintInfo.Columns.Count > m)            {                string colName = dtPrintInfo.Columns[m].ColumnName;                if (colLists.Contains(colName))                {                    m++;                    continue;                }                else if (string.Equals(colName, "EZLabelCopies"))                {                    m++;                    continue;                }                else                {                    dtPrintInfo.Columns.RemoveAt(m);                }            }        }        private static void PrintInfo(LabelFormatDocument btFormat, DataTable dtPrintInfo)        {            bool bSerializedLabels = btFormat.PrintSetup.SupportsSerializedLabels;            bool bCopies = btFormat.PrintSetup.SupportsIdenticalCopies;            int nCopyies = 0;            // 去除多余的字段            RemoveMuchFields(btFormat, ref dtPrintInfo);            if (dtPrintInfo.Columns.Count <= 1)            {                return;     // 没有要打印的字段了            }            for (int i = 0; i < dtPrintInfo.Rows.Count; i++)            {                string copies = dtPrintInfo.Rows[i]["EZLabelCopies"].ToString();                nCopyies = copies.Length > 0 ?
