Printing Grid Lines

Most of us display the gridlines in our spreadsheets. Oddly enough, Excel doesn't print those gridlines by default. If you want to print gridlines, you'll need to turn on that feature. To do so, choose File, Page Setup. Click the Sheet tab, then select the Gridlines option in the Print section. Click OK.
If the gridlines are printing and you don't want them printed, simply turn them off by deselecting the Gridlines option in the Print section.
