    hello,

    I am having a small problem and i don`t know the reason. I set that

    1- If you click Print button then print.php page will be printed automatically.

    2- if you submit a form then print.php page will be printed automatically.

    Problem is on second option. Page gets printed automatically perfect but if i click Print button again it does not print the page again.

    I am using firefox. 


    <script language="javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
    
        <script type="text/javascript"> 
        function loadiFrame(src) 
        { 
            $("#iframeplaceholder").html("<iframe id='myiframe' name='myname' src='" + src + "' frameborder='0'  vspace='0'  hspace='0'  marginwidth='0'  marginheight='0' width='1'  scrolling='no'  height='1' />"); 
        } 
     
        $(function() 
        { 
            $("#printbutton").bind("click",  
                function() {  
                    loadiFrame('print.php');  
                    $("#myiframe").load(  
                        function() { 
                            window.frames['myname'].focus(); 
                            window.frames['myname'].print();     
    					 } 
                     ); 
                } 
            ); 
        }); 
        </script>
    
    <?
    if (isset($_POST['formSubmit'])) 
    {
    echo "form submitted";
    ?>   
    <script type="text/javascript"> 
        $(document).ready(function(){ 
        $('#printbutton').trigger('click'); 
       });
    </script>  
    <? } ?>  
    </head>
    
    <body>
    <table border="1">
      <tr>
        <td><input type="button" id="printbutton" value="  Print  " /><div id="iframeplaceholder"></div></td>
      </tr>
    </table>
    
    
    <form action="auto.php" method="post">
    <input name="formSubmit" type="submit" value="Submit" />
    </form>
    </body>

    Think I have managed to solve it. According to this post, it's a bug in Firefox. It works if you add a counter that makes each iframe name unique.

    
        <script type="text/javascript"> 
        var counter = 0;

        function loadiFrame(src) 
        { 
            counter++;
            $("#iframeplaceholder").html("<iframe id='myiframe' name='myname" + counter + "' src='" + src + "' frameborder='0'  vspace='0'  hspace='0'  marginwidth='0'  marginheight='0' width='1'  scrolling='no'  height='1' />"); 
        } 
     
        $(function() 
        { 
            $("#printbutton").bind("click",  
                function() {  
                    loadiFrame('print.php');  
                    $("#myiframe").load(  
                        function() { 
                            window.frames['myname' + counter].focus(); 
                            window.frames['myname' + counter].print();     
    					 } 
                     ); 
                } 
            ); 
        }); 
        </script>

    You're welcome :)

    I'm surprised the bug has not been fixed yet, that post is more than two years old! :eek:

    My one is the latest one. I have to use firefox because it is the only one you can use to print things without having windows print dialog box.

    In Firefox, just type “about:config” to address bar and add a new Boolean preference item named “print.always_print_silent” then set value of the newly-added item to “true“. Then it prints without having print dialog box!
