* 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
