Which option must be selected for all sheets within a workbook to be printed?

To print all sheets within a workbook, you need to select the appropriate option in your spreadsheet program. Here's how to do it in two popular spreadsheet programs:

1. Microsoft Excel:
- Open your Excel workbook.
- Click on the "File" tab at the top left corner of the Excel window.
- In the menu that appears, click on "Print" or press the shortcut key "Ctrl + P" on your keyboard.
- In the Print Settings section, look for the option "Print Active Sheets" or "Print Entire Workbook."
- Make sure this option is selected to print all sheets within the workbook.
- Adjust any other printing settings as desired.
- Finally, click the "Print" button to start printing.

2. Google Sheets:
- Open your Google Sheets workbook.
- Click on the "File" tab at the top left corner of the Google Sheets window.
- In the drop-down menu, click on "Print" or press the shortcut key "Ctrl + P" on your keyboard.
- A Print Preview window will open.
- In the Print Settings section, you should see an option called "Sheets." It may be labeled as "All Sheets" or "Selected Sheets."
- Make sure to select the option to print all sheets within the workbook.
- Adjust any other printing settings as desired.
- Finally, click the "Print" button within the Print Preview window to start printing.

It's important to note that the specific steps may vary slightly depending on the version and interface of the software you are using. However, the general process should be similar across most spreadsheet programs.
