A user prints a spreadsheet in duplex mode.

Comprehensive and Detailed In-Depth Explanation:

Changing the page orientation (e.g., from portrait to landscape) allows wider columns to fit on one side of the page. This maintains readability while continuing to use duplex printing.

Option A: Disabling duplex defeats the goal of printing on both sides.

Option B: May help, but could make the document harder to read if the font is too small.

Option D: Unlikely to resolve formatting issues related to layout and dimensions.
