Invoice printing

Hi,
I have done a simple page where the labels get its values from the database and i have set the labels in an invoice format.
Now i would like to add a print, email & print preview button. How can i do this?
Thanks

You could set the function window.print() (https://developer.mozilla.org/en/DOM:window.print) on a button or image to get the print dialog. To send mails, you'd need to code using server-side language like PHP.

Thanks abduraooft,
How can i set my page so that it prints on an a4. Is there any print preview command?
thanks

Target your task to decide what you want to do first. This definitely does not belong in the PHP snippets forum, but I cannot move it until you decide what you want first. Looks to me like JS / XML-FO for starters.
