formatting and saving single pages in side-by-side view?

Is there a way to take a PDF and save it so that it is saved to open and appear (and print) in side-by-side page view?

I have a document with single pages and want to have them appear 1x1 so that they can be printed like this at a copy shop for a reader for students.

Is this possible?

If it's possible for documents that are already in a single page format, is it also possible for docs that are cropped to APPEAR in single page format? Let me explain: the text originally has Latin on the left side and English on the right. Cropping out the Latin produces a file that appears as English only, but 1 page of text per view. I'd like it to PRINT with 2 pages per view. But I am not sure how—unless it's just by saving the PDF in a two page view. When I save it that way it does open as 1x1 (left/right pages, e.g. p. 1-2, pp. 2-3 (as single views)). Maybe that's all that's needed?

thanks very much.
