How do I make an excel sheet print horizontally instead of vertically?

I’m making an Excel worksheet for work and I need it to print out length wise rather than heigth wise. In other words if i take the paper, and put it on one of it’s longsides, I want to be reading it from top to bottom. Whereas if I put it how it’s printing now, with one of the short sides down, that is reading it top to bottom.

How do I set it up to be horizontal rather than vertical? Thanks!
