.net 用USB操控新北洋标签打印机
老师要给招生办写一个艺术招生考试评分系统，以下是打印条形码部分，这一部分就是我昨晚奋战一晚的结晶啊！网上找不到任何资料，仅凭打印机器附送的一份儿帮助文档。没有完全是从无到有，从零开始的啊！一步一步都是试出来的，光标签纸都浪费了三四米！
现在回头想，其实也没什么深奥的东西，只是比较偏重于硬件底层。做完这个打印机的工作原理我倒了解了不少！主要的还是对打印机进行二次开发！
首先，你需要三个新北洋的dll类包：bpladll.dll，ByUSBInt.dll，LabelUSBPrintDll.dll
光有这三个类包是不够的，应为这三个包不是.net语言写的，所以还要自己新建一个.net的类包当做引导层，导入bplad.dll包。以下是我自己写的一个CUST.dll包：
