如何使用 Cordova 在 Android 上实现打印？

Question

我想在 Android 应用程序中实现打印功能，我正在使用 AngularJS。我试过下面的代码，但它只适用于浏览器，它不适用于 Android。

AngularJS：

$scope.print = function (divName) {
    var w = window.open();
    w.document.write($('#' + divName).html());
    w.print();
    w.close();
}

HTML：

<img ng-click="print('print');" class="card-img-top image-responsive" src="./plugins/images/print.png" alt="Card image cap">


<div id="print" style="display:none;">
    <style>
        @page {
            size: auto;
            margin: 7mm;
        }

        @media all {
            .page-break {
                display: none;
            }
        }

        @media print {
            .page-break {
                display: block;
                page-break-before: always;
            }
        }
    </style>
    <div class="row">
    </div>
</div>

我已经尝试了@VicJordan 提供的解决方案，但它给出了以下错误。

Answer 1

它适用于我的 javascript

var dowloadurl  = "/.../sample.pdf" // Here your file location
window.cordova.plugins.FileOpener.openFile(
   dowloadurl,
   onSuccessFileOpen,
   onErrorFileOpen
);
    
var onSuccessFileOpen = function (data) {
    alert('onSuccessFileOpen');
};

function onErrorFileOpen(err) {
    alert('message: ' + err);
}

Answer 2

我也有同样的问题。 尝试使用cordova-plugin-printer 插件来实现。它会解决你的问题。从您的代码看来，您希望通过id 打印div。以下是上述插件的各种用法：

打印整个 HTML 页面：

var page = location.href;

cordova.plugins.printer.print(page, 'Document.html');

从页面的一部分打印内容：

var page = document.getElementById('legal-notice');

cordova.plugins.printer.print(page, 'Document.html');

打印一些自定义内容：

var page = '<h1>Hello Document</h1>';

cordova.plugins.printer.print(page, 'Document.html');
