1. Reduce content: re-examine your resume, and delete or simplify some unimportant or redundant information to make it suitable for double-sided printing.

2. Format adjustment: adjust the font, font size, line spacing and other format settings of the resume to reduce the space occupied by the content. You can try to reduce the font size or line spacing to save space.

3. Use single-sided printing: If the resume content can't adapt to double-sided printing, you can choose to use single-sided printing. Although this will increase the consumption of printing paper, it can ensure the integrity of your resume.

4. Print attached pages: If your resume is too rich to fit all on one piece of paper, you can consider printing attached pages. Put the extra content on another piece of paper and mark the relevant additional information in your resume.
