How to Make Gridlines Print in Microsoft Excel 2007 Spreadsheets

1.
Select the 'Page Layout' tab. It is located on the 'Ribbon,' the group of icons above the work area in Excel.
2.
Put a check in the 'Print' box. Once on the Page Layout Tab, look toward the right side and you will see a group called 'Gridlines.' This will cause the gridlines to show when you print your spreadsheet.
3. If you change your mind and would like to have the gridlines hidden on print jobs again, simply remove the check from the 'Print' box.
