I would like to know if it's possible to use javascript to open a popup window containing an image, and at the same time have the print dialog show. Once someone clicks on print, the popup closes.
Is this easily attainable?
Another great solution!! All credit goes to Codescratcher
<script>
function ImagetoPrint(source)
{
return "<html><head><scri"+"pt>function step1(){\n" +
"setTimeout('step2()', 10);}\n" +
"function step2(){window.print();window.close()}\n" +
"</scri" + "pt></head><body onload='step1()'>\n" +
"<img src='" + source + "' /></body></html>";
}
function PrintImage(source)
{
var Pagelink = "about:blank";
var pwa = window.open(Pagelink, "_new");
pwa.document.open();
pwa.document.write(ImagetoPrint(source));
pwa.document.close();
}
</script>
PRINT
See the full example here.
popup = window.open();
popup.document.write("imagehtml");
popup.focus(); //required for IE
popup.print();
Use this in the head block
<script type="text/javascript">
function printImg() {
pwin = window.open(document.getElementById("mainImg").src,"_blank");
pwin.onload = function () {window.print();}
}
</script>
use this in the body block
<img src="images.jpg" id="mainImg" />
<input type="button" value="Print Image" onclick="printImg()" />
This code will open YOUR_IMAGE_URL in a popup window, show print dialog and close popup window after print.
var popup;
function closePrint () {
if ( popup ) {
popup.close();
}
}
popup = window.open( YOUR_IMAGE_URL );
popup.onbeforeunload = closePrint;
popup.onafterprint = closePrint;
popup.focus(); // Required for IE
popup.print();

Yea, just put the image on the screen, and then call window.print(); in javascript and it should popup.
(This is how Google Maps/Google Calendar do printing)
This works in Chrome:
<body ><img src="image.jpg" alt="" style="display: block; width: 100%; height: 100%;">
<script type="text/javascript">
window.onload = function() {
window.print();
setTimeout(function() {
window.close();
}, 1);
};
</script>
</body>
I just spent 45 minutes on this "SIMPLE" problem, trying to get it the way I wanted it to operate.
I had an image inside an img tag, dynamically generated by a jQuery Barcode plugin that I had to print. I wanted it to print in another window and afterwards close the window. This was all supposed to happen after the user clicked a button inside a jQuery Grid plugin, inside a jQuery-UI dialog along with jQuery-UI dialog extender applied to it.
I adjusted everyone answers till I finally came up with this, maybe it can help someone.
w = window.open(document.getElementById("UB-canvas").src);
w.onload = function () { w.print(); }
w.onbeforeunload = setTimeout(function () { w.close(); },500);
w.onafterprint = setTimeout(function () { w.close(); },500);
The setTimeout is not just for shits and giggles, it's the only way I found Firefox 42 would hit those functions. It would just simply skip the .close() functions until I added a breakpoint to it, then it worked perfectly. So I'm assuming it created those window instances before it could apply the onbeforeload event function and onafterprint event functions, or something.
I wrote a coffee script function that does that (but without opening a new window):
#print_img = (url) ->
$children = $('body').children().hide()
$img = $('<img>', src: url)
$img.appendTo('body')
$img.on 'load', ->
window.print()
$(this).remove()
$children.show()
Or if you prefer in javascript:
this.print_img = function(url) {
var $children, $img;
$children = $('body').children().hide();
$img = $('<img>', {
src: url
});
$img.appendTo('body');
$img.on('load', function() {
window.print();
$(this).remove();
$children.show();
});
};
This function makes sure that the elements on the body are hidden and not redrawn into the DOM.
It also makes sure that the image is loaded before calling print (if the image is too large and the internet connection is slow, it may take a while to load the img, if you call print too soon, it will print an empty page)

I am working on angular4 print functionality and i want to open print preview in new tab by default along with print popup window. I am not able to figure out how to pass data from parent window to child window to do the same. Can someone suggest something?
Use Following Code :
This will open this page in another tab and will open print pop up.
Page will take some time to load so use setTimeout according to your need.
var getPrint = window.open(document.URL, '_blank');
setTimeout(getPrint.print(), 3000);
Had the same situation while trying to allow user to view and print QR image in new tab. Here is how I got it done:
prepareQRForPrint(source: string) {
return "<html><head><style type='text/css' media='print'>#media print { #page { size: auto; margin: 0;} body { margin:1.6cm; } }</style><script>function step1(){\n" +
"setTimeout('step2()', 2);}\n" +
"function step2(){window.print();window.close()}\n" +
"</scri" + "pt></head><body onload='step1()'>\n" +
"<img style='width:800px;height:1000px;' src='" + source + "' /></body></html>"
}
printPreviewQR(source: string) {
let Pagelink = "about:blank";
var pwa = window.open(Pagelink, "_new");
pwa.document.open();
pwa.document.write(this.prepareQRForPrint(source));
pwa.document.close();
}
And invoked as:
QR-Code
This will work in Angular 12
/*
Use ViewChild to reference the element that contains the content that should be printed.
*/
#ViewChild('PackageSlipPrint', { static: true }) printableRef?: ElementRef;
print() {
var printdata = this.docRef.nativeElement.outerHTML;
var tab = window.open('') as Window;
tab.document.open();
tab.document.write(printdata);
setTimeout(() => {
tab.stop();
tab.print();
tab.close();
}, 300);
}
How to print a PDF in Firefox?
This function works in Chrome but not in Firefox
function print_pdf(url){
var id = 'iframe', html = '<iframe id="'+id+'" src="'+url+'" style="display:none"></iframe>';
$('#main').append(html);
$('#'+id).load(function(){
document.getElementById(id).contentWindow.print();
}
}
error
Error: Permission denied to access property "print"
Firefox: Permission denied to access property "print"
This is a bug in firefox. Locally it can be disabled by going to about:config and set the property of pdfjs.disabled to true. Only possible workaround is to use a server-side script and modify the pdf. Using php you could use fpdf and embed extensions to implement js (inclunding the print() function) or simply convert the pdf to an image, return the url and print it. You could use FPDI to modify the existing pdf. I will give you an example on how I got it to work with PHP.
Generating a PDF file with inline javascript (autoprint) using FPDI and PDF_JS
require_once('fpdf.php');
require_once('fpdi.php');
class PDF_JavaScript extends FPDI {
var $javascript;
var $n_js;
function IncludeJS($script) {
$this->javascript=$script;
}
function _putjavascript() {
$this->_newobj();
$this->n_js=$this->n;
$this->_out('<<');
$this->_out('/Names [(EmbeddedJS) '.($this->n+1).' 0 R]');
$this->_out('>>');
$this->_out('endobj');
$this->_newobj();
$this->_out('<<');
$this->_out('/S /JavaScript');
$this->_out('/JS '.$this->_textstring($this->javascript));
$this->_out('>>');
$this->_out('endobj');
}
function _putresources() {
parent::_putresources();
if (!empty($this->javascript)) {
$this->_putjavascript();
}
}
function _putcatalog() {
parent::_putcatalog();
if (!empty($this->javascript)) {
$this->_out('/Names <</JavaScript '.($this->n_js).' 0 R>>');
}
}
}
class PDF_AutoPrint extends PDF_JavaScript
{
function AutoPrint($dialog=false)
{
//Open the print dialog or start printing immediately on the standard printer
$param=($dialog ? 'true' : 'false');
$script="print($param);";
$this->IncludeJS($script);
}
function AutoPrintToPrinter($server, $printer, $dialog=false)
{
$script = "document.contentWindow.print();";
$this->IncludeJS($script);
}
}
$pdf=new PDF_AutoPrint();
$pdf->setSourceFile("mozilla.pdf");
//Open the print dialog
$tplIdx = $pdf->importPage(1, '/MediaBox');
$pdf->addPage();
$pdf->useTemplate($tplIdx, 10, 10, 90);
$pdf->AutoPrint(true);
$pdf->Output('generated.pdf', 'F');
Now you can simply append the generated pdf to your page and the included javascript will call the print() function. You do not even have to call it manually anymore. However, in firefox this will only work with visibility: hidden and not with display: none.
function print_pdf(url){
var iFrameJQueryObject = $('<iframe id="iframe" src="'+url+'" style="visibility: hidden"></iframe>');
$('#foo').append(iFrameJQueryObject);
}
print_pdf('mozilla_generated.pdf');
Chrome: Security Error (cross-origin)
The pdf should be located at the same host. Firefox was okay with other domains in my tests, but chrome gave me cross-origin errors.
Firefox: Printed page includes about:blank only
You will get an empty page in firefox (jsfiddle), because it will print the iframe before it has loaded any content. Mentioned methods like $(document).onload() won't help, since they only wait for the DOM to load and setTimeout() can still result in errors, since you do not know how long it takes the iFrame to load.
You can simply resolve this issue by using jQuery's load(). (doc) This will give you the possibility to use a callback function as parameter.
if a "complete" callback is provided, it is executed after post-processing and HTML insertion has been performed. The callback is fired once for each element in the jQuery collection, and this is set to each DOM element in turn.
Code Example 1
function print_pdf(url){
var id = 'iframe', html = '<iframe id="'+id+'" src="'+url+'" style="display:none"></iframe>';
$('body').append(html);
// wait for the iFrame to fully load and call the print() function afterwards
$('#' + id).load(function () {
document.getElementById(id).contentWindow.print();
});
}
Alternatively you could directly create an jQuery object and use jQuery's on() (doc) to attach any event handler.
Code Example 2 (jsfiddle)
function print_pdf(url){
var iFrameJQueryObject = $('<iframe id="iframe" src="'+url+'" style="display:none"></iframe>');
$('body').append(iFrameJQueryObject);
iFrameJQueryObject.on('load', function(){
$(this).get(0).contentWindow.print();
});
}
Edit, Updated
Try using window.onload event , document.createElement() , onload event , setTimeout() with duration set to 2000 , setting src of iframe after appending element to document
window.onload = function() {
function print_pdf(url){
var id = "iframe", frame = document.createElement("iframe");
frame.setAttribute("id", id);
frame.setAttribute("width", "800px");
frame.setAttribute("height", "600px");
frame.setAttribute("allowfullscreen", "true");
frame.setAttribute("name", "printframe");
document.body.appendChild(frame);
frame.onload = function() {
this.requestFullScreen = this.mozRequestFullScreen
|| this.webkitRequestFullScreen;
this.requestFullScreen();
setTimeout(function() {
print()
},2000)
}
frame.setAttribute("src", url);
}
print_pdf("http://zeitreisen.zeit.de/wp-content/uploads/2014/09/pdftest2.pdf");
}

PDFs have Javascript support. I needed to have auto print capabilities when a PHP-generated PDF was created and I was able to use FPDF to get it to work:
http://www.fpdf.org/en/script/script36.php
#clarkk i would recommend to use something more powerful which has been covered from many people my suggestion is to use http://pdfmake.org/#/ .
I have use this pdfmake in my datatables and it works absolutely perfect. Keep in mind if you print more then 10 000 rows from tables or something it run out the memory of the browser :)
I haven't use this for a while, but this what I was used to do to print pdf's from an iframe...
function printfile() {
window.frames['objAdobePrint'].focus();
window.frames['objAdobePrint'].print();
}
<iframe src="urlOfPdf" name="objAdobePrint" id="objAdobePrint"></iframe>
<button onclick="printfile();">Print</button>
You can implement print function without create new iframe (only with css) to prevent security problems:
var style = document.createElement("style");
style.setAttribute("media", "print"); //style.setAttribute("media", "screen,print");
style.appendChild(document.createTextNode(""));
document.head.appendChild(style);
var width = $("#printDiv").width();
var height = $("#printDiv").height();
style.sheet.insertRule("body { width: 210mm !important, height: 25.4mm !important; visibility: hidden; }", 0);
style.sheet.insertRule("#printDiv { visibility: visible; position: fixed !important;top: 5px; left: 5px; width:" + width + "px;height:" + height + "; page-break-after: avoid;}", 0);
window.focus();
window.print(true);
style.remove();
Print a pdf with javascript or jquery
Create a iframe in html:
<iframe id="pdf-iframe">
Then change the src of that iframe and on load, print it:
$('#pdf-iframe').attr("src", pdf_url).load(function(){
document.getElementById('pdf-iframe').contentWindow.print();
});
Or, you might want to try https://mozilla.github.io/pdf.js/
I am using javascript to periodically replace a .png picture, which ist viewed fullscreen as the only content of a site. No matter how I try, in Firefox, after being loaded (as seen via firebug), the new image is always drawn from top to bottom. This takes some seconds. Is there any way to prevent this and show the picture all at once?
This is my current javascript code:
function preloadScreenshotPeriodically(){
var new_screenshot = new Image();
new_screenshot.src = "screenshot.png?defeat_firefox_caching=" + counter;
new_screenshot.id = "screenshot";
counter = counter + 1;
new_screenshot.onload = function(){
loadScreenshot(new_screenshot);
setTimeout("preloadScreenshotPeriodically();", 5000);
};
}
function loadScreenshot(new_screenshot){
document.getElementById("screenshot").parentNode.replaceChild(new_screenshot, document.screenshot);
}
I also tried to use two images, one of them hidden. Then loading the picture in the hidden one and swapping them. Same results :/
In an other version, I fetched the image with Ajax and after loading is complete, changed the url of the img-tag. My hope was, that the browser would recognize the picture had already been loaded and fetch it from the browsercache rather than loading it. But this didn't happen and I ended up with two requests to the server for one picture and the same slow drawing of it as in my other trys.
edit:
Now I tried it like suggested in answer 1. While it works just fine if I switch the picture when I load the next one (I don't want this), trying to switch it as soon as it is loaded (what I want) results in a blank window (very short) and visible loading of the picture as described above.
this works:
<body>
<style type="text/css">
#loaderWin { display:block; height:1px; width:1px; overflow:hidden; }
</style>
<div id="imagewin"></div>
<div id="loaderWin"></div>
<script type="text/javascript">
var screenshotCount=0;
function showFirstImage() {
loadNextImage();
}
function showNewImage() {
loadNextImage();
}
function nextImageLoaded() {
// swapImage();
}
function loadNextImage() {
swapImage();
screenshotCount = screenshotCount +1;
var nextImage = "<img id='loaderWinImg' src='screenshot.png?x="+screenshotCount+"' onload='nextImageLoaded()' />";
document.getElementById('loaderWin').innerHTML = nextImage;
}
function swapImage() {
document.getElementById("loaderWinImg").onload = '';
var newimage=document.getElementById('loaderWin').innerHTML;
document.getElementById('imagewin').innerHTML = newimage;
}
var showImages = setInterval("showNewImage()",15000);
showFirstImage();
</script>
</div>
</body>
</html>
this doesn't work:
<body>
<style type="text/css">
#loaderWin { display:block; height:1px; width:1px; overflow:hidden; }
</style>
<div id="imagewin"></div>
<div id="loaderWin"></div>
<script type="text/javascript">
var screenshotCount=0;
function showFirstImage() {
loadNextImage();
}
function showNewImage() {
loadNextImage();
}
function nextImageLoaded() {
swapImage();
}
function loadNextImage() {
screenshotCount = screenshotCount +1;
var nextImage = "<img id='loaderWinImg' src='screenshot.png?x="+screenshotCount+"' onload='nextImageLoaded()' />";
document.getElementById('loaderWin').innerHTML = nextImage;
}
function swapImage() {
// loadNextImage();
document.getElementById("loaderWinImg").onload = '';
var newimage=document.getElementById('loaderWin').innerHTML;
document.getElementById('imagewin').innerHTML = newimage;
}
var showImages = setInterval("showNewImage()",15000);
showFirstImage();
</script>
</div>
</body>
</html>
The problem can be seen here (in firefox problem like described above, in chrome there are no pauses between pictureloads and there is a blank window in between picture changes): http://sabine-schneider.silbe.org:1666/test.html
And here, what Rob suggested in answer 1 without any changes (displays the picture fine in firefox, but not in chrome - there I get a blank window in between picture changes): http://sabine-schneider.silbe.org:1666/test0.html
sounds like the image is "progressive" ( interlaced) and the preload needs more time for it to complete download.
You can set a width and height to the image also for a more stable presentation
( poss )
using
?defeat_firefox_caching=" + counter;
means you never cache the image ( which has confused me about your question ) - remove that line( unless you need it for something you haven't mentioned)
update: Can you try ...
<style type="text/css">
#loaderWin { display:block; height:1px; width:1px; overflow:hidden; }
</style>
<div id="imagewin"></div>
<div id="loaderWin"></div>
<script type="text/javascript">
var screenshotCount=0;
function showNewImage() {
screenshotCount = screenshotCount +1;
var newimage=document.getElementById('loaderWin').innerHTML;
document.getElementById('imagewin').innerHTML = newimage;
var nextImage = "<img src='screenshot.png?defeat_firefox_caching="+screenshotCoun+"'/>";
document.getElementById('loaderWin').innerHTML = nextImage;
}
var showImages = setInterval("showNewImage()",5000);
</script>
thank you all for helping me previously with my Javascripting problems. My current problem is that I need to open & close a new window on an image's onMouseOver & onMouseOut, respectively, but if the new window onMouseOver == true then I don't want the new window to close.
I am sure there is a simple solution, but I can't seem to figure out a way to cancel the image's onMouseOut="closeDetails();" if the user hovers over the New Window. Below is most of the code I am dealing with. Thanks in advance for your help.
<body>
<img name="img1" id="img1" onMouseOver="windowDelay(this);"
onMouseOut="closeDetails();" src="images/127.jpg" height="240" width="166"/>
</body>
<script language="JavaScript" type="text/javascript">
// This opens the movie details pop-up after an
// half second interval.
function windowDelay(thatImg)
{
winOpenTimer = window.setTimeout(function() {openDetails(thatImg);}, 2000);
}
// This is the function that will open the
// new window when the mouse is moved over the image
function openDetails(thatImg)
{
// This creates a new window and uses the hovered image name as the window
// name so that it can be used in the that window's javascript
newWindow = open("", thatImg.name,"width=400,height=500,left=410,top=210");
// open new document
newWindow.document.open();
// Text of the new document
// Replace your " with ' or \" or your document.write statements will fail
newWindow.document.write("<html><head><title>Movies</title>");
newWindow.document.write("<script src='myDetails.js' type='text/javascript'>");
newWindow.document.write("</script></head>");
newWindow.document.write("<body bgcolor='white' onload='popUpDetails();'>");
newWindow.document.write("... SOME OTHER HTML....");
newWindow.document.write("</body></html>");
// close the document
newWindow.document.close();
}
// This is the function that will call the
// closeWindow() after 2 seconds
// when the mouse is moved off the image.
function closeDetails()
{
winCloseTimer = window.setTimeout("closeWindow();", 2000);
}
// This function closes the pop-up window
// and turns off the Window Timers
function closeWindow()
{
// If popUpHover == true then I do not want
// the window to close
if(popUpHover == false)
{
clearInterval(winOpenTimer);
clearInterval(winCloseTimer);
newWindow.close();
}
}
function popUpDetails()
{
// This will be used to prevent the Details Window from closing
popUpHover = true;
// Below is some other javascript code...
}
</script>
I would recommend against using a new browser window for this task. Try something like this:
var popup = {
open = function () {
if (this.element == null) {
// create new div element to be our popup and store it in the popup object
this.element = document.createElement('div');
this.element.id = "myPopup";
// you don't need a full html document here. Just the stuff you were putting in the <body> tag before
this.element.innerHTML = "<your>html</here>";
// Some bare minimum styles to make this work as a popup. Would be better in a stylesheet
this.element.style = "position: absolute; top: 50px; right: 50px; width: 300px; height: 300px; background-color: #fff;";
}
// Add it to your <body> tag
document.body.appendChild(this.element);
// call whatever setup functions you were calling before
popUpDetails();
},
close = function () {
// get rid of the popup
document.body.removeChild(this.element);
// any other code you want
}
};
// The element you want to trigger the popup
var hoverOverMe = document.getElementById("hoverOverMe");
// set our popup open and close methods to the proper events
hoverOverMe.onmouseover = popup.open;
hoverOverMe.onmouseout = popup.close;
That should do it. It's much easier to control than a new browser window. You will want to tweak the CSS yourself.
EDIT:
Here are instructions to do this with an actual window. To reiterate, using an actual window is not the best way to accomplish this task. A stylized div tag to look like a window is better because it offers more control, as well as standardized functionality across browsers. However, if you must use a window, here it is:
// You can use many principles from the example above, but I'll give the quick version
var popup;
var hoverOverMe = document.getElementById("hoverOverMe");
hoverOverMe.onmouseover = function () {
popup = window.open("path_to_content", "popup");
};
hoverOverMe.onmouseout = function () {
popup.close();
};
It works, but not very well (IMHO). If the user has their settings such that new windows open in new tabs (as I do), then a tab will open up. Javascript has no control over that. In Firefox, the new tab will open and gain focus, at which point it immediately closes because hoverOverMe had its onmouseout event fired (which obviously closes the window). I imagine you'd have this same problem with an actual window, too.
I found the following JS online, which functions like:
If an image is clicked, open the image in new window and prompt for print. Once printed the window closes. I need this script modified to click a print link it prints an image then closes the new image window. So I want to change from clicking the image itself to clicking a link that says print image.
Here is the code:
<script type="text/javascript">
/* <![CDATA[ */
function makepage(src)
{
// We break the closing script tag in half to prevent
// the HTML parser from seeing it as a part of
// the *main* page.
return "<html>\n" +
"<head>\n" +
"<title>Temporary Printing Window</title>\n" +
"<script>\n" +
"function step1() {\n" +
" setTimeout('step2()', 10);\n" +
"}\n" +
"function step2() {\n" +
" window.print();\n" +
" window.close();\n" +
"}\n" +
"</scr" + "ipt>\n" +
"</head>\n" +
"<body onLoad='step1()'>\n" +
"<img src='" + src + "'/>\n" +
"</body>\n" +
"</html>\n";
}
function printme(evt)
{
if (!evt) {
// Old IE
evt = window.event;
}
var image = evt.target;
if (!image) {
// Old IE
image = window.event.srcElement;
}
src = image.src;
link = "about:blank";
var pw = window.open(link, "_new");
pw.document.open();
pw.document.write(makepage(src));
pw.document.close();
}
/* ]]> */
</script>
<img src="fortune.jpg" onclick="printme(event)" />
I do not know any JS so I apologize. I only do php/mysql.
Best Regards!
Jim.
<img src="someurl.jpg" id="imgid' />
Print the image
function printme(id)
{
var src = document.getElementById(id).src;
var link = "about:blank";
var pw = window.open(link, "_new");
pw.document.open();
pw.document.write(makepage(src));
pw.document.close();
}
In the old method, the printme function knows what image should be printed: the same image that was clicked; when you change the trigger, you need to tell the function explicitly what image you want to print. That is why we are adding an id to the image and pass it to printme function. But if you only have one image on the page, or if a spacial relation exists (like the link always being the immediate next node after the image), then we can do it differently and need no id.
I don't know what your link looks like, but assuming it's just a plain anchor:
Change from:
<img src="fortune.jpg" onclick="printme(event)" />
To:
<img id="printableImage" src="fortune.jpg" onclick="printme(event)" />
<a href="javascript:void(0);" onclick="printme('printableImage')" />
Then alter the printme() function to retrieve the image src from the passed in image element id (jQuery makes this easy):
function printme(printableImageId)
{
var src = $('#' + printableImageId).attr('src');
// the rest of the logic...
}
You'll need to modify the printMe function a bit, doing this should fix it:
function printme(evt)
{
if (!evt) {
// Old IE
evt = window.event;
}
var anchor = evt.target;
if (!anchor) {
// Old IE
anchor = window.event.srcElement;
}
src = anchor.href;
link = "about:blank";
var pw = window.open(link, "_new");
pw.document.open();
