How to print PDF spreads as single pages?

I've created an InDesign layout which contains spreads, 2 letter-size sheets side by side on each PDF "page."

I'm trying to figure out how to print the PDF so that each letter sized sheet prints onto its own letter sized page of paper. Can't figure out what Acrobat print settings to use. Or perhaps something I have to tweak in the InDesign file?

Here's the example PDF I'm trying to print:

Any help is much appreciated! Thanks in advance.
