C#调用斑马打印机打印条码标签(支持COM、LPT、USB、TCP连接方式和ZPL、EPL、CPCL指令)

在批量打印商品标签时一般都要加上条码或图片，而这类应用大多是使用斑马打印机，所以我也遇到了怎么打印的问题。

一种办法是用标签设计软件做好模板，在标签设计软件中打印，这种办法不用写代码，但对我来说觉得不能接受，所以尝试代码解决问题。

网上搜索一番，找不到什么资料，基本都是说发送ZPL、EPL指令到打印机，而且还是COM/LPT口连接打印机。后来研究.net的打印类库，发现是用绘图方式打印至打印机的，也叫GDI打印，于是思路有了点突破，那我可以用报表工具画好标签，运行报表时，把结果输出位图，再发送至打印机。

后来又找到一种更好的办法，利用标签设计软件做好模板，打印至本地文件，把其中的ZPL、EPL指令拷贝出来，替换其中动态变化的内容为变量名，做成一个模板文本，在代码中动态替换变量，再把指令输出至打印机。

折腾了几天，终于把这两种思路都实现了，顺便解决了USB接口打印机的ZPL、EPL指令发送问题。

今天有点困，改天再详细讲解一下这两种思路的具体实现。

==============================================================================================================
如何获取标签设计软件输出至打印的ZPL指令？安装好打印机驱动，修改打印机端口，新建一个打印机端口，类型为本地端口，端口名称设置为C:\printer.log，再用标签设计软件打印一次，此文件中就有ZPL指令了。

2012-06-02：发布代码ZebraPrintHelper.cs。

==============================================================================================================

2013-01-17：发布代码ZebraPrintHelper.cs，修正BUG，新增TCP打印支持Zebra无线打印QL320+系列打印机。已经生产环境实际应用，支持POS小票、吊牌、洗水唛、条码、文本混合标签打印。因涉及公司源码，只能截图VS解决方案给大家看。
