C#实现的ZPL条码打印类完整实例
时间:03月28日

本文实例讲述了C#实现的ZPL条码打印类。分享给大家供大家参考,具体如下:

using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Diagnostics;
using System.Drawing;

     * 打印中文先引用Fnthex32.dll
      dll控件常规安装方法(仅供参考):
      下面是32系统的注册bat文件
      可将下面的代码保存为“注册.bat“,放到dll目录,就会自动完成dll注册(win98不支持)。
      @echo 开始注册
      copy Fnthex32.dll %windir%\system32\
      regsvr32 %windir%\system32\Fnthex32.dll /s
      @echo Fnthex32.dll注册成功
      @pause
      下面是64系统的注册bat文件
      @echo 开始注册
      copy Fnthex32.dll %windir%\SysWOW64\
      regsvr32 %windir%\SysWOW64\Fnthex32.dll /s
      @echo Fnthex32.dll注册成功
      @pause
