我正在尝试使用 katzer https://github.com/katzer/cordova-plugin-printer 的打印插件

我按照上面说的做了，但我不知道如何调用 index.html 文件中的函数来查看插件是否正常工作。

这是 index.html

【解决方案1】：

放置一个cordova onDeviceReady事件。

document.addEventListener("deviceready", onDeviceReady, false);

// Cordova Device Ready.
function onDeviceReady() {

cordova.plugins.printer.isAvailable(
    //Check whether the printer is available or not.
    function (isAvailable) {
         //Enter the page location.
         var page = location.href;
         cordova.plugins.printer.print(page, 'Document.html', function () {
         alert('printing finished or canceled')
});
    }
);

}

打印整个 HTML 页面

// index.html 的 URI var page = location.href; cordova.plugins.printer.print(page, 'Document.html', function () { alert('打印完成或取消') });
从页面的一部分打印内容

// DOM 节点或字符串 var page = document.getElementById('legal-notice'); cordova.plugins.printer.print(page, 'Document.html', function () { alert('打印完成或取消') });
打印自定义特定内容

// DOM 节点或字符串

var page = '<h1>Hello Document</h1>';    
cordova.plugins.printer.print(page, 'Document.html', function () {
    alert('printing finished or canceled')
});

打印远程网页

cordova.plugins.printer.print('http://blackberry.de', 'BB!!!', function () { alert('打印完成或取消') });
调整页面

cordova.plugins.printer.print('123', { name:'Document.html', Landscape:true }, function () { alert('打印完成或取消') });
在 iPad 上自定义大小和位置

// 选项一 cordova.plugins.printer.print('123', { bounds:[40, 30, 0, 0] }); // 选项二 cordova.plugins.printer.print('123', { bounds:{ left:40, top:30, width:0 height:0 } });

我收到错误“TypeError: cordova.plugins is undefined”

【解决方案2】：

就像其他答案所说，只需调用“cordova.plugins.printer.print()”函数进行打印。但是，这里的一大障碍是平台......

默认的cordorva 打印机插件还不支持“windows”平台。因此，如果您在 Windows 上工作，那就没有运气了。您必须将其构建为 App/Apk 并安装到您的手机上才能测试此功能。

如何针对每个移动平台构建它不在本主题范围内，是的，请参阅完整文档...

一种快速的方法是通过 Adobe PhoneGap build 构建项目，然后下载 apk 以查看它在您的手机上的工作方式。希望这会有所帮助。
