When you want to print an Excel spreadsheet, you may find that the data doesn't fit well on the page. There are a few things that you can do to try and make your printout fit on a page:

1. First, check the margins in your Excel spreadsheet. You can find the margins by going to Page Layout > Margins. If your margins are set too wide, your data may not fit on the page when you print it.
2. Second, check the orientation of your page. You can find this by going to Page Layout > Orientation. If you have your page set to landscape, it will take up more space on the page and may not fit when you print it.
3. Third, check the scaling of your page. You can find this by going to Page Layout > Scale. If your scaling is set too high, your data may not fit on the page when you print it.
4. Fourth, try printing in black and white. You can find this option by going to File > Print > Black and White. This may help if your data has a lot of color or graphics that are taking up too much space on the page.
5. Finally, if none of these options work, you may need to split your data into multiple pages. You can do this by going to Page Layout > Breaks > Insert Page Break.

If you follow these steps, you should be able to get your data to fit on a single page when you print it from Excel.
