Android進階——安卓調(diào)用ESC/POS打印機打印實例

更新時間：2017年04月07日 16:30:22 作者：河北-寶哥

本篇文章主要介紹了Android進階——安卓調(diào)用ESC/POS打印機打印實例，具有一定的參考價值，感興趣的小伙伴們可以參考一下。

前言

前一段時間由于工作需要，要研究一下安卓程序調(diào)用打印機打印小票，并且要求不能使用藍牙調(diào)用，研究了一下，可以利用socket連接，來實現(xiàn)打印功能。寫了個Demo，分享一下。

工具：一臺打印機（芯燁XP-80XX），一臺安卓測試機

開發(fā)環(huán)境：Android Studio 1.5

需求：點擊按鈕，實現(xiàn)打印小票功能，小票上除必要文字外，還要有二維碼。

封裝了一個Pos打印工具類：

其中，打印機的IP和端口號從打印機的屬性設(shè)置處可查。

MainActivity中進行調(diào)用：

}

附：小票中菜品的Bean類

public class FoodsBean { 
  private String name; 
  private String price; 
  private String number; 
  private String sum; 
 
  public String getName() { 
    return name; 
  } 
  public void setName(String name) { 
    this.name = 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; 
  } 
}
