安卓连接pos小票机和钱箱

安卓连接pos小票机和钱箱

2017-2-13来源：iOS开发人气：75

测试工具具体用到：

1、58热敏打印机

2、钱箱

3、Android Studio 2.2.2

4、测试平板一台

端口号打印机一般都是9100

首先把打印机固定ip设置好，然后所有设备连接到同一网络（不在同一网络连接不上）

钱箱看需求，直接插在打印机上就行了

布局就很简单写一个Button按钮就行，其他随意

再定义一个

public class FoodsBean {

    private String price;
    private String number;
    private String sum;

    public String getName() {
        return name;
    }

    }
    public String getPrice() {
        return price;
    }
    public void setPrice(String price) {
        this.price = price;
    }
    public String getNumber() {
        return number;
    }
    public void setNumber(String number) {
        this.number = number;
    }
    public String getSum() {
        return sum;
    }
    public void setSum(String sum) {
        this.sum = sum;
    }
}
