The file was created in InDesign CS5 and has to be saved as a .pdf. I want to view all of the spreads in the .pdf, but actually print them as single pages.
If the pages are exported to PDF as spreads, that's how they are going to print. You can export as single pages and set the initial view in Acrobat Pro so the file opens as spreads, with a single cover page if needed, but it won't look exactly the same as a true spread and it won't stop a user from changing the view.
Personally, I hate PDFs exported as spreads because they're really hard to navigate (same for two-column text meant to be read on screen).
