I do not think this is a way to get a parallel listing of two files. But you can use the Vim "Convert to HTML" tool on each of the two files that will be posted, and print them separately. You can then stack them side by side to get the same effect.
Converting to HTML is a kind of "beautiful print" - it saves all the information about visual color / syntax / mix.
