Hide header and footer
According to default settings of Internet browsers additional information is printed on headers and footers, such as the date of printing, number of pages, address of the site printed.
This function can be switched off with the Page Setup menu point of the File menu of the browser.
Set the Header and Footer functions on switched off mode. After this data in the header and footer will not be printed.
Setting Margins
It is possible that some data cannot be printed on a page as they do not fit the page, and some data on the right side will be missing.
In this case choose the above mentioned menu point. Set here the margins to a smaller value in a way that data can fit the page (Margins, Left, Right)
