1) use ob_start() and related functions in your script. Yhis is only adding three lines of PHP code in your existing script without changing anything to it.

2) send the bufferred output ( a simple string $variable) to wherever you want. To the printer of the customer, it's not possible, but you can send him back a page displaying the contents and then doing a (javascript)
<script>document.print();</script>
(or the like)

Okay, you lost me.
What do you mean when you say:

"i want to send the dynamic page to printer directly without showing to user"

The use has to confirm the printer job?
You could target the default printer of the visitor btw...
You could use javascript and use php together with an onload command.

In head:

<SCRIPT LANGUAGE="JavaScript">
<!--
function yo(text){
text=document
print(text)
}
//-->
</script>

then:

<body onload="javascript:yo();">

Is this something your trying to do?

Is the printer local or remote?

This is a PHP (which is server side) forum. So when you say print, I don't think it to be unreasonable to assume that you mean when a user comes to your site, you (i.e. a script on the server) wants to generate a local (i.e. serverside) report.

If you mean you want the USER to get a report, then this is client side and JavaScript is the quickest way. I would also recommend using a hidden frame so that nothing is actually shown to the user.

If you really do mean server side reporting (i.e. you have a line printer recording hits/logs/etc), then you can could use fopen() to open the printer (LPT1 on windows for example, I think something like lpr on *ix, not sure).

You could then use fprintf to write out formatted data.

Richard.
