How to Print Titles, Gridlines, and Headings in Excel
You can specify rows and columns to repeat on each printed page. You can also select whether you want to print cell gridlines and row and column headings.
The letters and numbers that serve as the row and column headings don’t print by default. Neither do the worksheet gridlines. You can turn them on for printing if needed.
Click the Page Layout tab.
Click the Print Titles button.
Under Print, click the Gridlines check box to show or hide gridlines.
Select the Row and column headings check box to show or hide row and column headings.
