On Windows, Firefox's Page Setup dialog allows a limited amount of customization of your headers and footers for printouts. Basically you have left, center, and right regions at the top and bottom of the page with the option to use one of the dynamic values (e.g., date, page number) or the text of your choice. This article describes those options: [[How to print websites]]. Did you want to do something more customized?

Hi vijay777pawar, as far as I know, there is currently no way for script in a website to modify margins in Firefox or other browsers. There probably is a better place to discuss or propose a new API, maybe some group working on HTML5 or updating JavaScript. In the meantime, there is PDF.
