I think this is one of those instances where it is up to you to decide whether what the manufacturer is telling you is true or not. I'd start my analysis by trying to think what the manufacturer has to gain by lying to you about it. I am not coming up with anything, but that may just be a lack of imagination on my part.
I don't think anyone is lying here. It may be the individual who was tasked with writing the user manual just makes up a reason to put the paper in one way rather than the other. These things happen.

I really don't want to get into a blame game. No doubt the manufacturer has constraints that we don't fully appreciate. I'm just interested to establish the factual basis for their recommendation about print orientation. I don't have facilities to do detailed assays, so I wondered whether there was any published literature, or whether anyone had any insights. I think I've drawn a blank. Thanks, everyone, for your thoughts.

So one guy ordered the plastic parts with dimples on one side for reasons known only to him, and the guy writing the instruction manual just made up a reason why he did so? Sounds plausible. Sort of. Not really. Fortunately, the end user can put paper in the slots anyway he wants to.
