Using window.print () or an alternative on Android devices

On Android devices (I tested Nexus 5, Nexus 10, Galaxy S4, and Galaxy Tab 3), the window.print() command window.print() nothing in JavaScript. As far as I can tell, it doesn't even log an error.

I know that most, if not all of these browsers can print, because you can use the Chrome mobile menu to select "print".

Why window.print() not trigger the behavior you expect (opening the client print menu)? And is there an Android alternative for window.print() ?

This Documentation clearly states: " The command is supported on iOS, Chrome on Windows, and Safari and Chrome on Mac. It is not supported on Android ."

Android phones have no built-in print support yet, so window.print() will not work. This means that you need to use a third-party print application. You can find some alternatives in this article .

Use Google Cloud Print (GCP) - no application required. The user must configure the printer through GCP.

This example uses the GCP gadget

I am working on a simulation problem and came up with this solution:

 $(document).ready(function($) { var ua = navigator.userAgent.toLowerCase(); var isAndroid = ua.indexOf("android") > -1; //&& ua.indexOf("mobile"); $('button.print').click(function(e) { e.preventDefault(); if (isAndroid) { // https://developers.google.com/cloud-print/docs/gadget var gadget = new cloudprint.Gadget(); gadget.setPrintDocument("url", $('title').html(), window.location.href, "utf-8"); gadget.openPrintDialog(); } else { window.print(); } return false; }); }); 
 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <button class="print">Print this page</button>

I didn’t have time to check if this works, I don’t have an Android device right now. I would like some feedback on this; -)

I think the direct print () method is disabled on devices by default. I have not seen so many phones or other Android devices with a printer, but via USB it should be possible, of course.

Instead, it is recommended that you save the content / page in pdf format and print it through the cloud print service. A.

Currently, the window.print () function works fine on my Android 5.0.1 device with both Chrome and the default browser.
