I have a php page which has a chart, a date picker(calendar) and a few buttons.

I want to add another button Print Chart which ONLY prints the chart & not the entire page
,in a local printer.

I am trying to do this by a having another script(which only outputs a chart) and using the javascript function 'window.print'

html

<input type=button onClick=printChart()   value=Print Chart>

javascript

function printChart(){



    var myParameters = window.location.search;// Get the parameters from the current page



    var URL = http://my_server/my_folder/my_script_that_outputs_only_my_chart.php+myParameters;



    var W = window.open(URL);



    W.window.print(); // Is this the right syntax ? This prints a blank page and not the above URL

}

I tried the above code - it doesnt work. A blank page gets printed.

Is there a way to print a target URL ? If yes, is it possible to print it without having to open a new window ?

Thanks for your time
