I presume you are trying to print some web page content from browser print option.
Browser adds header / footer. Position of header (date, url, etc...) is browser specific. In Google Chrome it can be only enabled or disabled (maybe there are formatting options inside Chrome settings) in Firefox content of header/footer can be customized in print options.
