老師要給招生辦寫一個藝術招生考試評分系統，以下是打印條形碼部分，這一部分就是我昨晚奮戰一晚的結晶啊！網上找不到任何資料，僅憑打印機器附送的一份兒幫助文檔。沒有完全是從無到有，從零開始的啊！一步一步都是試出來的，光標簽紙都浪費了三四米！
現在回頭想，其實也沒什么深奧的東西，只是比較偏重於硬件底層。做完這個打印機的工作原理我倒了解了不少！主要的還是對打印機進行二次開發！
首先，你需要三個新北洋的dll類包：bpladll.dll，ByUSBInt.dll，LabelUSBPrintDll.dll
光有這三個類包是不夠的，應為這三個包不是.net語言寫的，所以還要自己新建一個.net的類包當做引導層，導入bplad.dll包。以下是我自己寫的一個CUST.dll包：
