Excel Printing Format Issues

I'm not new to Excel and have the latest version via Office 365. I'm contracting with a company who provided their own invoice which has worked fine since mid-June. Today I went to print my invoice for my files and suddenly I'm only receiving the output in Landscape orientation.

I checked my printer settings (Epson Workforce 545) and all was set properly for portrait printing. I checked page layout and everything is set to portrait, fit to page and all the standard items. I've never changed any settings. I made sure my printer has the latest settings/drivers, I've rebooted the printer & computer. Back & forth and the spreadsheet refuses to print in portrait even though all the settings are set to portrait.

And assistance would be greatly appreciated.

Thanks,

Betty
