Have you actually tried this? I am not sure that you have.
If you have and it worked, then that's great (for you). But, it only makes matters worse: because it doesn't on mine (and others too) which implies Apple have made a consistency error - and a right clanger at that too.
If it didn't actually work (and I am fairly sure it doesn't) then that only proves my point on two scores:
First, this function will only reverse print direct to paper - NOT to PDF. When invoking this parameter with 'Save to PDF, OS X completely 'forgets' & does it regular order anyway.
Second - and arguably most important - to do it this way is intrinsically self-defeating because of it's arcaneness. Even if it is designed/expected behaviour, the Apple platform prides itself on being straightforward, for use by everyone regardless of technical ability which makes this notion daft. To put another way, I am engineer of c.20 years experience - 12 in UNIX software development, and it took me a number of attempts before I found this option (hence my post here).
Given the enormity of this function, it's also worthy to note that the built-in Apple help doesn't say much about it either.
So sadly it's still 'nil-póint' (as the French would say) to Apple.
And in case you think I sound ungrateful for continuing to burn the wick, let me assure you that I aint. Ta lots for this - it's definitely the most worthy post here and exactly what we come here for.
Now where's my bucket of water... 😉
