Which option in Excel is used to alter the scaling of a page for printing?

The option utilized to alter the scaling of a page for printing in Excel is found under the "File" menu, specifically in the "Print" section, through "Page Setup." This feature allows users to manage how their data is formatted to fit on a printed page. By accessing Page Setup, you can adjust the scaling options, such as choosing to fit the selected content onto one page or scaling to a specific percentage.

This control is crucial when preparing documents for print, ensuring that all information fits properly and is easily readable, which enhances both the aesthetics and functionality of the printed output. The scaling settings available here help to optimize the arrangement of elements on a page, especially for larger datasets that may not otherwise fit within standard page dimensions.

Other choices relate to different functionalities in Excel that do not specifically address the alteration of printing scaling.
