Presumably, the huge inefficient PS document would have gone through pstops before being sent over the wire. Would that have compacted it substantially? I should have thought to capture it for testing.

pstops doesn't try to compress or reformat the document. At best it might filter out whole pages, but generally it just adds the printer commands (print this duplex, etc.) to the document and sends it on to the printer.
