How do I print grids on the spreadsheet?

How do I print grids on the spreadsheet? I know it can be done but I just spent the better part of an hour trying to figure it out and can’t. There should be a toolbar icon to take care of it but I can’t find any. PLEASE HELP ME!

File (menu) > Print Preview (menu) > Format Page (button) > Sheet (tab) > Grid (check box in Print group)
