None whatsoever. It's my current printer, after an Epson P600 that I purchased new and used for a year (that one's sitting in a closet now), and thicker paper feed is easier and more consistent with the Pro 100 than the P600.
Here's something to consider. One can read lots of discussion about gloss differential. I found that, unless examining an area with virtually no image, pigment inks on any glossy 'art' paper were too shiny period. There was no differential. I hate reflections. I tried a large number of papers from many manufacturers and all suffered from this problem. Moving on to matt papers, the best one with a P600 was Hahnemuhle Photo Rag Ultra Smooth, but dmax, while better than most, was still inadequate. The matt paper 'blahs' seem unavoidable.
In the course of exchanging prints with another photographer who was also on a 'paper quest,' but who uses a Pro 100, we discovered that dye inks don't suffer excessive shine on glossy papers. Our ultimate conclusions agreed: optimum results came from Hahnemuhle FineArt Baryta Satin printed on a Pro 100. I strongly recommend anyone seeking a beautiful print (which also provides the side benefit of being nicely rigid and flat in the hand) give that combination a chance.
