更新记录

2.2（2022-03-22）

1.新增扫描OK、报错、成功提示音。

2.1（2022-03-11）

1.动态设置TSC打印机的标签纸宽度、标签纸高度、和标签纸间隙。

2.0（2021-12-10）

1.优化插件获取位置权限问题，示例项目在onLoad方法里获取权限，而不是onShow方法里，避免初次获取权限时不停调用问题而奔溃。

平台兼容性

原生插件通用使用流程：

1. 购买插件，选择该插件绑定的项目。
2. 在HBuilderX里找到项目，在manifest的app原生插件配置中勾选模块，如需要填写参数则参考插件作者的文档添加。
3. 根据插件作者的提供的文档开发代码，在代码中引用插件，调用插件功能。
4. 打包自定义基座，选择插件，得到自定义基座，然后运行时选择自定义基座，进行log输出测试。
5. 开发完毕后正式云打包

付费原生插件目前不支持离线打包。
Android 离线打包原生插件另见文档 https://nativesupport.dcloud.net.cn/NativePlugin/offline_package/android
iOS 离线打包原生插件另见文档 https://nativesupport.dcloud.net.cn/NativePlugin/offline_package/ios

注意事项：使用HBuilderX2.7.14以下版本，如果同一插件且同一appid下购买并绑定了多个包名，提交云打包界面提示包名绑定不一致时，需要在HBuilderX项目中manifest.json->“App原生插件配置”->”云端插件“列表中删除该插件重新选择

一、实例化插件和提示语插件：

var printModule = uni.requireNativePlugin("ZXA-BluetoothPrinterModule")
const modal = uni.requireNativePlugin('modal');

二、初始化蓝牙，连接蓝牙功能，并返回以配对设备

printModule.openBluetooth({
},
(ret) => {
        console.log("ret.data:  " + JSON.stringify(ret.data));
        this.connectionList = ret.data;
});

三、通过蓝牙扫描设备

printModule.scanDevice({},
                (ret) => {
                console.log("ret.data:  " + JSON.stringify(ret.data));

         if (ret.data.endscan == true) {
                            uni.showToast({
                                icon: 'none',
                                title: '扫描结束！'
                            })
                        } else {
                            this.devices.push({
                                devicename: ret.data.devicename,
                                macaddress: ret.data.macaddress,
                            })
                        }
                    });

四、关闭蓝牙扫描

printModule.closeBluetooth();

五、连接选定的蓝牙

​ uni.showLoading({ ​ title: "蓝牙连接中", ​ mask: true ​ }); ​
​ printModule.connectDevice({ ​ 'macaddress': item.macaddress, ​ 'devicename': item.devicename ​ }, ​ (ret) => { ​ modal.toast({ ​ message: "蓝牙" + ret.devicename + "---" + ret.macaddress + "---" + ret.state, ​ duration: 1.5 ​ }); ​
​ this.currDev = item; ​ uni.hideLoading(); ​

 });

​

六、传入参数，打印标签

printModule.startPrintLabel({
       'dataArray': this.dataArray
    },
     (ret) => {
});

七、TSC打印机指令

 //打印文本
 //文本说明： TEXT x,y,"font",rotation,x-multiplication,y-multiplication,"content"
 export function  getTextStr (x, y, font, x_, y_, str) {
    var data = "TEXT " + x + "," + y + ",\"" + font + "\"," + 0 + "," + x_ + "," + y_ + "," + "\"" + str + "\"\r\n";
    return data;
}

//打印条形码
//条形码说明：  BARCODE x,y,"code type",height,human readable,rotation,narrow,wide,"content"
export function  getBarStr (x, y, codetype, height, readable, narrow, wide, content) {
    var data = "BARCODE " + x + "," + y + ",\"" + codetype + "\"," + height + "," + readable + "," + 0 + "," + narrow + "," + wide + ",\"" + content + "\"\r\n";
    return data;
}

//画线
//画线说明： BAR x,y,width,height
export function  getBarLineStr (x, y, width, height) {
    var data = "BAR " + x + "," + y + "," + width + "," + height + "\r\n";
    return data;
}

//打印二维码
//二维码说明： QRCODE x,y,ECC level,cell width,mode,rotation,"data string"
export function  getQRCodeStr (x, y, level, width, mode, content) {
    var data = "QRCODE " + x + "," + y + "," + level + "," + width + "," + mode + "," + 0 + ",\"" + content + "\"\r\n"
    return data;
}

八、TSC打印机将指令添加到打印的data中，传输到插件方法中

 //初始化dataArray
 //设置打印宽度、高度、打印纸的间隙，添加打印文本
this.dataArray.push({
                printwidth:75,
                printheight:42,
                printgap:0,
                printkey: getTextStr(50, 10, "ROMAN.TTF", 7, 7, labelTitle)
            }) 
//添加打印文本
this.dataArray.push({
     printkey: getTextStr(50, 50, "ROMAN.TTF", 7, 7, labelIdStr)
}) ;
//添加二维码 
this.dataArray.push({
        printkey: getQRCodeStr(390, 80, "L", 4, "A", "L2021012600000733")
}) ;

//添加画线
this.dataArray.push({
        printkey: getBarLineStr(30,170,500,2)
}) ;

​

九、ESC打印机指令

 //打印文本
 //ESC打印数据格式
this.escDataArray.push({
        printType: "text",
        printContent: "万达广场欢迎您",
        textAlign: "center",   //left:居左对其  center：居中对其  right：居右对齐
        size: "max"  //max：大   normal：正常大小
});

//打印一维条形码
this.escDataArray.push({
        printType: "barcode",
        printContent: "2019563352660",
        textAlign: "center",   //left:居左对其  center：居中对其  right：居右对齐
});

//打印二维码
this.escDataArray.push({
        printType: "qrcode",
        printContent: "2019563352660",
        textAlign: "center",  //left:居左对其  center：居中对其  right：居右对齐
});

//打印本地图片
var filePath = plus.io.convertLocalFileSystemURL("static/logo.png");
this.escDataArray.push({
        printType: "image",
        typeName: "local",
        printContent: filePath,
        textAlign: "center",
});

//打印网络图片
this.escDataArray.push({
        printType: "image",
        typeName: "network",
        printContent: "http://www.html5-app.com/gprinter.png",
        textAlign: "center",
});

//切纸命令
this.escDataArray.push({
        printType: "cutPaper",
});

十、CPCL打印机指令

 //打印文本
 //CPCL打印数据格式
 this.cpclDataArray.push({
      printType: "text",
      printContent: "Sample", //打印内容
      textAlign: "center", //left:居左对其  center：居中对其  right：居右对齐
      coordinateX: 0, //坐标X
      coordinateY: 30, //坐标Y
      height: 730,
      qty: 1,
      magWidth: 1,//放大或缩小的倍数
      magHeight: 1//放大或缩小的倍数
 });

//打印文本
this.cpclDataArray.push({
          printType: "text",
            printContent: "这是CPCL打印指令",
            textAlign: "left",
            coordinateX: 30,
            coordinateY: 65,
});

this.cpclDataArray.push({
            printType: "text",
            printContent: "你好,欢迎使用CPCPL指令打印",
            textAlign: "left", //不需要就传空字符串
