A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
I've also ran into this bug, Windows 10 2004 64-bit and Excel 365. The workaround I'm doing doesn't involve signing out and in, I just make sure Excel is closed, set scaling to 100%, open Excel, and set scaling back to 175%. In my case as long as Excel is opened while display scaling in Windows is set to 100%, it will keep the correct printing layout. As long as Excel is kept opened, I can open other files and will print correctly, as far as I can tell.
This also works with Remote Desktop, Log into RD with 100% scaling, open Excel, log off RD, and log back in with the scaling I want.
But geez, more than 2 years and nothing, Microsoft. Really?
