You can add your company logo, page numbers, and other information to each page of a printed view or report, making your page look more professional and often more useful. With Microsoft Project, you can add information to the header (text that prints at the top of every page) or to the footer (text that prints at the bottom of every page).
You can also add your project’s legend. The legend is an explanatory list that, by default, appears on every page of a printed view. You can choose to print the legend on every page, on a separate page, or on none of the pages of your view. You can add legends only to the Calendar, Gantt Chart, and PERT Chart views.
