After about a year of adequate performance, now my printer will not print Hahnemuehle Photo Rag Ultra Smooth (308g) in anything larger than 8.5x11. I get the usual round of paper skew, print error, etc. Larger sized Epson Velvet are OK. BUT I really like the Hahnemuehle. The Epson Velvet is very pebbly and makes the images seem blurier. I think the problem with the Hahnemuehle, as one repair technician mentioned, is that it can be slightly curved or bent and this is the problem. SO, what else could I use that's bright white and ultra smooth and very flat? In 13x19 and 17x22 sizes? Any recommendations?
