Ionic 2 应用程序通过商米 V1 打印 [英] Ionic 2 application to print via Sunmi V1

问题描述

对于使用商米 V1 打印的 ionic 2 应用程序，通过执行为打印机添加了本机插件

For an ionic 2 app to print using Sunmi V1, added native plugin for printer by executing

cordova plugin add cordova-plugin-printer

首先我检查了打印机是否可用

First I checked whether the printer is available by

checkPrinter() {
    this.printer.check().then(function () {
        alert("Printer available");
    }, function () {
        alert("Printer not available");
    });
}

它会提醒打印机可用"

但是下面的方法没有提示任何信息

But the below method doesn't prompt any message

printData() {
    this.printer.isAvailable().then(function () {
        this.printer.print("Test Data").then(function () {
            alert("Printed");
        }, function () {
            alert("Printing error");
        });
    }, function () {
        alert('Unavailable');
    });
}

所以我直接调用Printer.print方法如下

So I called Printer.print method directly as below

printData(){
    this.printer.print("Test Data").then(function () {
        alert("Printed");
    }, function () {
        alert("Printing Error");
    });
}

此方法打开打印对话框以选择打印机

This method opens Print dialog to choose printer

如果我从下拉列表中选择所有打印机"来选择打印机而不是另存为 PDF"，则会出现搜索屏幕并继续搜索...

If I select 'All Printers' from the dropdown to select printer instead of 'Save as PDF', then the search screen appears and keeps on searching...

是否缺少某些配置，或者是否可以使用 cordova 打印机插件与 POS 打印机交互?

Is some configuration missing or is it possible to interact with POS printers using cordova printer plugin?

谢谢.
