Sure, at a prior job we passed out hardcopies of a side-by-side diff before scheduling a peer review (including only the affected methods/functions).

No syntax highlighting, but it was quite useful. Off the top of my head, the two main benefits are: 1) You free up your computer for the review 2) You get a different form factor to interact with.

Regarding the first benefit, having a printout means you can use your computer to run the application, look up docs, and even (ironically) navigate the code in your IDE.

As for the second, having a printout means you can spread out the pages to compare different bits of code, draw diagrams, connect arrows, circle bits of code for notes, etc.

It was pretty useful.
