How to detect window.print() finish

Question

In my application, I tried to print out a voucher page for the user like this:

  var htm ="<div>Voucher Details</div>";
  $('#divprint').html(htm);
  window.setTimeout('window.print()',2000);

'divprint' is a div in my page which store information about the voucher.

It works, and the print page pops up. But I want to advance the application once the user clicks 'print' or 'close' in the browser's pop-up print dialog.

For example, I'd like to redirect user to another page after pop up window is closed:

window.application.directtoantherpage();//a function which direct user to other page

How can I determine when the pop up print window is closed or print is finished?

Answer 1

You can listen to the afterprint event.

https://developer.mozilla.org/en-US/docs/Web/API/window.onafterprint

window.onafterprint = function(){
   console.log("Printing completed...");
}

It may be possible to use window.matchMedia to get this functionality in another way.

(function() {

    var beforePrint = function() {
        console.log('Functionality to run before printing.');
    };

    var afterPrint = function() {
        console.log('Functionality to run after printing');
    };

    if (window.matchMedia) {
        var mediaQueryList = window.matchMedia('print');
        mediaQueryList.addListener(function(mql) {
            if (mql.matches) {
                beforePrint();
            } else {
                afterPrint();
            }
        });
    }

    window.onbeforeprint = beforePrint;
    window.onafterprint = afterPrint;

}());

On chrome (V.35.0.1916.153 m) Try this:

function loadPrint() {
    window.print();
    setTimeout(function () { window.close(); }, 100);
}

Works great for me. It will close window after user finished working on printing dialog.

Answer 3

compatible with chrome, firefox, opera, Internet Explorer
Note: jQuery required.

<script>

    window.onafterprint = function(e){
        $(window).off('mousemove', window.onafterprint);
        console.log('Print Dialog Closed..');
    };

    window.print();

    setTimeout(function(){
        $(window).one('mousemove', window.onafterprint);
    }, 1);

</script>

See https://stackoverflow.com/a/15662720/687315. As a workaround, you can listen for the afterPrint event on the window (Firefox and IE) and listen for mouse movement on the document (indicating that the user has closed the print dialog and returned to the page) after the window.mediaMatch API indicates that the media no longer matches "print" (Firefox and Chrome).

Keep in mind that the user may or may not have actually printed the document. Also, if you call window.print() too often in Chrome, the user may not have even been prompted to print.

You can detect when window.print() is finished simply by putting it in another function

//function to call if you want to print
var onPrintFinished=function(printed){console.log("do something...");}

//print command
onPrintFinished(window.print());

tested in Firefox,Google chrome,IE

Answer 6

window.print behaves synchronously on chrome .. try this in your console

window.print();
console.log("printed");

"printed" doesn't display unless the print dialog is closed(canceled/saved/printed) by the user.

Here is a more detailed explanation about this issue.

I am not sure about IE or Firefox will check and update that later

Answer 7

This Actually worked for me in chrome. I was pretty suprised.

jQuery(document).bind("keyup keydown", function(e){
    if(e.ctrlKey && e.keyCode == 80){
         Print(); e.preventDefault();
    }
});

Where Print is a function I wrote that calls window.print(); It also works as a pure blocker if you disable Print();

As noted here by user3017502

window.print() will pause so you can add an onPrintFinish or onPrintBegin like this

function Print(){
    onPrintBegin
    window.print();
    onPrintFinish(); 
}

Answer 8

Tested IE, FF, Chrome and works in all.

    setTimeout(function () { window.print(); }, 500);
    window.onfocus = function () { setTimeout(function () { window.close(); }, 500); }

Answer 9

Given that you wish to wait for the print dialog to go away I would use focus binding on the window.

print();

var handler = function(){
    //unbind task();
    $(window).unbind("focus",handler);
}

$(window).bind("focus",handler);

By putting in the unbind in the handler function we prevent the focus event staying bond to the window.

Print in new window with w = window.open(url, '_blank') and try w.focus();w.close(); and detect when page is closed. Works in all browsers.

w = window.open(url, '_blank');
w.onunload = function(){
 console.log('closed!');
}
w.focus();
w.print();
w.close();

Window close after finish print.

Answer 11

It works for me with $(window).focus().

var w;
var src = 'http://pagetoprint';
if (/chrom(e|ium)/.test(navigator.userAgent.toLowerCase())) {
    w = $('<iframe></iframe>');
    w.attr('src', src);
    w.css('display', 'none');
    $('body').append(w);
    w.load(function() {
        w[0].focus();
        w[0].contentWindow.print();
    });
    $(window).focus(function() {
        console.log('After print');
    });
}
else {
    w = window.open(src);
    $(w).unload(function() {
        console.log('After print');
    });
}

Simplest way to detect if print has finished and close print window:

window.onafterprint = function(){ 
  window.onfocus = function(){  
    window.close();
  }
};
