Excel Page Formatting for Printing

Using MacBook Pro with Sonoma 14.6.1. Edited a two page Excel spreadsheet and sent it to print (Brother MFC-J6545DW). Original document is formatted to use narrow margins. Print job is OK. Edited second page again and sent it to print. Page printed with wide borders. Checked page layout menu and it was still set to narrow margins. Document also appears with narrow margins when viewed in Preview. I would very much appreciate any suggestions you might offer.

Thank you.
