Hello,

We will be happy to help you integrate QZ Print into your environment.  I would like to mention that we have a desktop version (QZ Tray), that uses WebSockets to talk to the browser, and therefore, will work with the latest version of Chrome.  QZ Print is the Java applet that uses NPAPI, which Chrome has blocked.

Have you successfully installed QZ Print?  You can navigate to our demo page at https://demo.qz.io/ to test that QZ Print is successfully installed and properly working.  This demo page is the sample.html that ships with our software in the demo folder.

This guide is a great starting point to view code examples to help achieve what you are looking for.  

If you need any more help or information, whether it's getting the software to work or implementing the code, please do not hesitate to contact us.

Regards,

Hi Thanks for your reply. I need more clarification on same.

My project is Java/JSF web application installed in Linux server, my clients need to print barcode by opening web application in their desktop and print to the printer connected in their network or their desktop.

Please advice how I should use the code which you have shared me as demo project to integrate my code as same :)

Hello,

As mentioned, this guide: https://qz.io/wiki/getting-started is a good starting point.  When loaded properly, the QZ Print applet will interact with the JavaScript running on the webpage.  Many of our clients will also use the sample.html page that ships with our software as a guide.  This file provides a good working example of our software interacting with a webpage.  You can open this file with a text editor of your choice to view the code that you may want to cherry pick to suit your needs.

You will find that some of the logic in the sample.html page is not needed, as some of it is used for our QZ Tray software.  Take a look at this guide: https://qz.io/wiki/qz-print-vs-qz-tray to see code that is not needed for QZ Print.

I hope this is enough information to get you started.  If you run into any problems or snags, we will be more than happy to look at your code to help integrate QZ Print into your environment.

https://qz.io/wiki/qz-print-vs-qz-tray returns ERROR 404 :(

Hi Kavi,

https://qz.io/wiki/qz-print-vs-qz-tray returns ERROR 404 :(

That wiki was written for clients migrating from the applet version to QZ Tray 1.9. QZ Tray 1.9 was the first desktop installer version, and included a wrapper around the old API. These versions are no longer supported.

If you're looking for a minimalist example, take a look at this guide: https://qz.io/wiki/2.0-getting-started#the-code

Thanks,

Hi, Kyle

Thanks for your reply.

I've been trying to make qz work on my desktop for the last 2 days already and unfortunatelly unsuccessfully :(

Where should I paste the code from https://qz.io/wiki/2.0-getting-started#the-code ?

Should I paste it in the <head> or in the <body> ?

I'd like to trigger the printing automatically when page loads with <body onload="print()">

I am trying all variations like pasting the code in the <head> and pasting the code in the <body> but neither works :(

This is my html which is not working:

<html>

<head>

    <meta content="text/html;charset=utf-8" http-equiv="Content-Type">

    <title>POS print by Kavi ...</title>

<script type="text/javascript" src="js/dependencies/rsvp-3.1.0.min.js"></script>

<script type="text/javascript" src="js/dependencies/sha-256.min.js"></script>

<script type="text/javascript" src="js/qz-tray.js"></script>

</head>

<body onload="print()">

<script>

function print() {

   var config = qz.configs.create("POS-58");

   var data = [

      'Data\n',

      'Should be simple data\n',

      'To be printed\n'

   ];

   qz.print(config, data).catch(function(e) {

       console.error(e);

   });

}

</script>    

<h1>Printing to POS !!!</h1>

</body>

</html>

Can you please help?

Thank you.
