How to remove the words "Sheet 1" and "Page 1" from printed output?

When I print a page using Llibreoffice Calc, I have the words “Sheet 1” at the top and “Page 1” at the bottom . How can I stop these being printed? Is this part of the page format and if so how do I stop it?

Go to Format > Page. You can set the Header and Footer off in the Header and Footer Tabs.

Thank`s Guys. Great Help. TEA BOY
