There are a few different ways to protect print settings in Excel. One way is to use the Print Area feature. This allows you to specify which cells you want to print, and then you can protect the print area so that it can't be changed. Another way to protect print settings is to use the Page Break Preview feature. This allows you to see how your data will be divided up into pages, and you can then protect the page breaks so that they can't be changed. Finally, you can also password-protect your workbook or worksheet, which will prevent anyone from making changes to the print settings.
To use the Print Area feature, first select the cells that you want to print. Then, go to the File tab and click on Print. In the Settings section, click on the drop-down menu next to Print Area and select Set Print Area. This will add a dotted line around the cells that you selected. To protect the print area, go back to the File tab and click on Protect Workbook. In the Protect Workbook dialog box, select Structure from the list of options and enter a password (if desired).
To use the Page Break Preview feature, go to the View tab and click on Page Break Preview. This will show you how your data will be divided up into pages based on the current page setup. To protect the page breaks, go back to the View tab and click on Protect Sheet. In the Protect Sheet dialog box, select Insert Columns, Delete Columns, Insert Rows, Delete Rows, Format Cells, Format Columns, or Format Rows from the list of options (depending on which actions you want to allow) and enter a password (if desired).
To password-protect your workbook or worksheet, go to the File tab and click on Info. Then click on Protect Workbook or Protect Worksheet from the list of options (depending on which one you want to protect). In the dialog box that appears, select Password from the list of options and enter a password.
