百富POS機A920安卓系統打印功能的實現

由於打印demo中隻有一些參數設置和基礎打印，也無法實現排版功能，後采用com.pax.gl.imgprocessing中的接口

IImgProcessing.IPage

生成bitmap實現打印，可支持打印排版，打印圖片等。

 

1、重要的引入jar包，一開始隻引入瞭第一個，然後是痛苦的bug排查。。。

2、根據API，添加打印功能，自己封裝瞭一個打印工具類

調用打印方法

new Thread(new Runnable() {

首先需要獲取IDal dal對象，再通過getPrinter()方法拿到printer

package com.hisun.pos.utils.printer;

import android.util.Log;

import com.hisun.pos.activity.CashierChoosePaymentActivity;
import com.pax.gl.IGL;
import com.pax.ippi.dal.interfaces.IDal;
import com.pax.ippi.emv.interfaces.IEmv;

public class GetObj {

    private static IDal dal;
    private static IGL gl;
    private static IEmv emv;

    // 獲取IDal dal對象
    public static IDal getDal() {
        dal = CashierChoosePaymentActivity.dal;
        if (dal == null) {
            Log.e("IPPITest", "dal is null");
        }
        return dal;
    }

    // 獲取IGL gl對象
    public static IGL getGL() {

        gl = CashierChoosePaymentActivity.gl;
        if (gl == null) {
            Log.e("IPPITest", "gl is null");
        }
        return gl;

    }

    // 獲取IEmv emv對象
    public static IEmv getEmv() {

        emv = CashierChoosePaymentActivity.emv;
        if (emv == null) {
            Log.e("IPPITest", "emv is null");
        }
        return emv;

    }

}

IDal dal對象可在MainActivity中註冊NeptuneUser對象拿到，dal = neptuneUser.getService().getDal();

    public static NeptuneUser neptuneUser;
    public static IDal dal;
    public static IGL gl;
    public static IEmv emv;
	
	@Override
    protected void setLayout() {
        setContentView(R.layout.activity_cashier_choose_payment);

        neptuneUser = NeptuneUser.getInstance(this);
        dal = neptuneUser.getService().getDal();
        gl = neptuneUser.getService().getGl();
        emv = neptuneUser.getService().getEmv();
    }
	
    @Override
    protected void onResume() {
        super.onResume();
        neptuneUser.register();
    }

    @Override
    protected void onPause() {
        super.onPause();
        neptuneUser.unRegister();
    }
