.net 用USB操控新北洋标签打印机

news/2024/12/4 16:32:39/

  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:

 

using System; using System.Collections.Generic;
