C#版OPOS打印(基于北洋OPOS SDK二次开发包,支持EPSON和北洋、佳博、商祺等支持标准ESC/POS指令的POS打印机)
C#版OPOS打印
- 基于北洋OPOS SDK二次开发包,支持EPSON和北洋、佳博、商祺等支持标准ESC/POS指令的POS打印机
- 支持并口,串口,网口,USB口,驱动方式等多种端口
- 支持开关钱箱
- 支持条码打印
- SDK中支持的其他设备的控制(扫描枪等)
北洋SDK中只有VB和Delphi的例程,所以参照Delphi转成了C#的版本,并集成到软件中实际应用。希望给需要了解C#使用OPOS SDK开发的朋友提供一些帮助。
废话少说,直接上代码。
