Dear @Michelle Wells,
Thank you for posting your question in the Microsoft Q&A forum.
Based on your description, you’re seeing an unwanted page border only in Print Preview or when printing your Excel sheet. For better understand your situation, could you please provide more detail information as:
- Have you tried to print with another device to check whether the issue still persists or not?
- And try to copy that file then print again.
- Have you checked other users print that file have the same issue as you?
- Does it occur with only specific file, or all files have that issue?
- It would be grateful if you could provide screenshot and your Excel setting so we could check and support more effective
Looking forward to your update
