前面写到斑马打印机的ZPL措辞，及常用的命令。本次写下C#如何调用ZPL措辞在斑马打印机上进行打印。
C#调用斑马打印机打印紧张用到两个库：Fnthex32.dll和SMT.ZEBRA.dll，利用方法：SMT.ZEBRA.dll在项目中引用，Fnthex32.dll只需把dll放到C:\Windows\SysWow64和C:\Windows\System32 文件夹中即可。其余把稳天生的程序假如32位，64位会报错。
代码实现：
紧张用到的方法：ZebraPrinter.PrintLabEx（string n_strTemplateFilePath, string n_strLabels, string n_strPrinterName）
第一个参数：n_strTemplateFilePath是ZPL命令的路径地址，编写好的ZPL命令格式是.TXT或者.ZPL格式，把稳假如大写。
第二个参数：n_strLabels标签数据凑集字符串，多个标签行用'|'分割,单个标签行数据内部用'^'(字段)分割或'~'(笔墨或条码)分割
第三个参数：n_strPrinterName是打印机名称。
代码如下：
