Silent printing in IE using activeX

Hello

I'm trying to pritn using adobe acrobat activeX

here is my code

<!DOCTYPE html>

<html>

<head>

    <title>Print Test</title>

    <meta charset="utf-8" />

    <script>

        function startPrinting() {

        var acrobatObj = document.createElement('object');

        acrobatObj.width = '500';

        acrobatObj.height = '500';

        acrobatObj.classid = 'clsid:CA8A9780-280D-11CF-A24D-444553540000';

document.body.appendChild(acrobatObj)

acrobatObj.src = 'test.pdf';

            window.setTimeout(

                function () {

                    acrobatObj.print();

                }, 1000);   // how big timeout?

        }

        window.onload = startPrinting;

    </script>

</head>

<body>

<div id="ext-gen289"></div>

</body>

</html>

It works nicelly

Now the question- if user has low bandwidth, the setTimeout to 1 second is not enough.

In fact soem of users need to wait 1 minute to donlload respective file. While the others on stronger network, can print normally withoin one second

Is there a wya how the activeX would notify me "i have whole content"

I tried to play with cache, cookies sent prom the server, buffered reponse or session with no luck so far

Thanks
