if want print after form validating , submitting, supposed in client side.

you can this:

<form name="myform" action="action.php" onsubmit="return validateform()" method="post">      name: <input type="text" name="fname">     <input type="submit" value="submit"> </form> 

then, validate form , print.

<script> function validateform() {     // validate form here     window.print(); } </script> 

hope helps.
