There are a few things you can do to use less paper when printing out your Excel spreadsheets. One way is to print on both sides of the paper. You can do this by going into the Page Layout tab and selecting the Print Titles button. Then, click on the Sheet tab and select Print
Another way to save paper is to adjust your margins. The default margin settings in Excel are 1 inch margins all around. You can change these by going into the Page Layout tab and selecting Margins. From there, you can select Narrow, which will give you 0.5 inch margins all around.
You can also scale your printouts so that they fit onto fewer pages. To do this, go into the Page Layout tab and click on Scale to Fit. From there, you can enter how many pages wide and tall you want your printout to be.
Finally, you can choose to print only a selection of your spreadsheet rather than the entire thing. To do this, first select the cells that you want to print by clicking and dragging over them. Then go into the File tab and click Print. In the Print dialog box that comes up, make sure that the Selection option is selected in the Print What drop-down menu.
By following these tips, you can save paper when printing out your Excel spreadsheets.
