The my_sales_data_final.xlsx workbook file is open.
Having previewed the sales data worksheet, you now have a better idea of the precise page layout you would like to define before printing the pages. You feel the printed sheets will work better in the landscape orientation, and you want to widen the page margins slightly. Additionally, you don't like the layout with all of the rows displayed on a single page, so you decide to change the scaling to fit all columns on a single page and make the column labels print on each page. You also decide to add headers and footers to the workbook to include the date of the sales meeting, a title for the workbook, and page numbers.
