the problem is i want the print button only appear when there is output..

I apologize if I am in the wrong forum so I hope somebody can help. I have a function which sends an emails to client everytime an order is processed. They have asked me to add a print button in the emails so they could just print the email. I have tried using javascript and call the window.print function but when I click the button nothing happens. I know that it is possible to add a print button in an email but I can't figure out what I am doing wrong. Here is some of the code use to create the email using paypal ipn script.
Code: [Select]
$body = "<html>".
"<head>".
              "<script type='text/javascript'>".
"//<![CDATA[ function PrintEmail(){ window.print(); } //]]> ".
"</script>".
"</head>".
"<body>".
"<a href='javascript:window.print()'>Print Page</a><br />".
"<input type='button' onclick='javascript:PrintEmail();' value='Print This Page' /><br /><b>Customer Name</b>: ".$name."<br />";

foreach($id_str_array as $key => $value){
$id_quantity_pair = explode(":", $value);
$product_id = $id_quantity_pair[0]; // Get the product ID
$cameo_color = $id_quantity_pair[1];
  $product_quantity = $id_quantity_pair[2]; // Get the quantity
$product_line1 = $id_quantity_pair[3]; // Get Line 1
$product_line2 = $id_quantity_pair[4]; // Get Line 2
$product_picture = $id_quantity_pair[5]; // Get picture
$discount_code = $id_quantity_pair[6];

              $body .= "<b>Product</b>: ".$product_id."<br />".
              "<b>Quantity</b>: ".$product_quantity."<br />".
              "<b>Engraving Line 1</b>: ".$product_line1."<br />".
"<b>Engraving Line 2</b>: ".$product_line2."<br />".
"<b>Your picture</b>: <img src='http://t3.sysguru.com/mcf/pictures/".$product_picture."' height='300' width='556' /><br />";
}
$body .= "<b>Total</b>: $".$_POST['mc_gross']."</body></html>";

$subject = "Transaction Completed";
$mailer->SendPayPalInfo($subject, $body);

I tried just calling the javascript print function with a link and aslo create a function and called the function from the button and neither of these methods work. here is the code which send the message out.
Code: [Select]
function SendPayPalInfo($subject, $body){
     $headers = "From: " .EMAIL_FROM_ADDR. "\r\n";
     $headers .= "Reply-To: ".EMAIL_FROM_ADDR."\r\n";
     $headers .= "MIME-Version: 1.0\r\n";
     $headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n";

     return mail(EMAIL_FROM_ADDR, $subject, $body, $headers);
}

Am I missing something in the headers of am I coding this wrong? Any help would be appreciated.

Code: [Select]
echo "<tr><td colspan='2'><input type='submit' value='Add Reply' onClick=\"window.location = post_reply.php?cid=".$cid."&tid=".$tid."\" /><hr /> ";
