When printing a timesheet in Internet Explorer 7 and higher you may often notice that the Web TimeSheet URL gets imprinted to the bottom or footer of the hardcopy. To turn off the header and footer information just once, use the Print Preview window and then click the button to Turn headers and footers on or off as described in the screenshot below,
