Across (horizontal)=Landscape. Vertical=Portrait
This is not a question, but my best guess of what you want to know is the word landscape.
Landscape orientation means the printout will be across the length of the page, while portrait orientation means it will be along the height of the page.
This question is not clear, but my best guess is that you are looking for landscape (print with the long edge of the paper on the top).
That is the way English is written.

Across the width. Portrait - width < height Lanscape width > height Typically achieved by rotating paper though a right angle!
