2008|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。
