Question : how to print a web page

Hello Experts,
On my website i 'd like put "print this page" img button to let visitors to see the page first then to print the page they are currently seeing.
I created print friendly CSS. I use onclick"window.print()" . it does the job, (without showing the page in a new window)
 
however i would like to present the print friendly page in a NEW window then user clicks "print button" then goes to printer

could you provide some codes

thanks in advance
