How nice that the 3880 can detect this, at least with Epson Legacy Baryta. As much as I like Hahnemühle Photo Silk Baryta 310, which I suspect is very similar, telling which side is the print side is not super-easy for me, and I've put the wrong one through the Pro-100, I think twice. It makes a bit of a mess of things. Fortunately there are not too many papers that have given me that problem.
