jsp 调用条码打印机，求大家帮忙啊，谢谢了！！

[kxc123]

我用web想调用客户端的条码打印怎么实现呢，能调exe就行。
我用net use不行。
有没有别的办法，用applet可以吗，大家帮忙啊。。谢谢

用JNative 调用条码打印机提供的dll文件，传参即可...
我以前做了，条码能打印，但是打印出来中文一直乱码 ，后面有别的事情就没做了
调用的是立象了X-1000V PPLB条码打印机
代码没写完，很乱，仅作参考

applet 等插件，得有本地安全授权，才能访问本地打印机。

一般activeX的比较多。

[kxc123]

用activeX具体怎么做呢，我没用过请大家具体教一下谢谢了.

ocx控件。用vb写的客户端页面脚本.cab文件。然后签到页面调用，我的资源里有，可以供你参考
