    I have a ticket booking system in Joomla.

    When user clicks on ticket link a ticket is shown on the site.

    I am using a barcode.php file to generate the barcode image for ticket number.

    Now there are 2 scenarios I used to print ticket.

    1. When I print that ticket using window.print() or Ctrl+P, 2 pages get printed even though my ticket content is only single page.

    2. When I use following javascript code to print specific part of the page, barcode image is not generated. 

      function print_specific_div_content(){
    var content = "<html>";
    content += document.getElementById("divToPrint").innerHTML ;
    content += "</body>";
    content += "</html>";

    var printWin = window.open('','','left=0,top=0,width=552,height=477,toolbar=0,scrollbars=0,status =0');
    printWin.document.write(content);
    printWin.document.close();
    printWin.focus();
    printWin.print();
    printWin.close();
}

    My requirements are:

    Ticket should be printed only on single page.

    Any help or suggestion will be appreciated.

    Thanks.

    EDIT 1 :

    I modified my function as follow, but unfortunately it shows new window but no print dialog. :(

    function print_specific_div_content(){
    var win = window.open('','','left=0,top=0,width=552,height=477,toolbar=0,scrollbars=0,status =0');
    var handler = function() {
      win.print();
      win.close();
    };
    if(win.addEventListener)
        win.addEventListener('load', handler, false);
    else if(win.attachEvent)
        win.attachEvent('onload', handler, false);

    var content = "<html>";
    content += document.getElementById("divToPrint").innerHTML ;
    content += "</body>";
    content += "</html>";
    win.document.write(content);
    win.document.close();
}

    Reset to default 10

    When printing just the content, you need to wait for the document to load before printing so that the images will be loaded:

    function print_specific_div_content(){
    var win = window.open('','','left=0,top=0,width=552,height=477,toolbar=0,scrollbars=0,status =0');

    var content = "<html>";
    content += "<body onload=\"window.print(); window.close();\">";
    content += document.getElementById("divToPrint").innerHTML ;
    content += "</body>";
    content += "</html>";
    win.document.write(content);
    win.document.close();
}
