I am in the same situation as you. I bought the same printer a month and a half ago. I have a friend who had a compagny called PrintMaker based in Kauai. He uses Epson printers. He helped me to set it up and his advice to me about paper is to buy few sample papers ( 81/2-11’ ) and try them with wildlife and from there decide which one to use. He helped me choose paper from different compagnies, Hahnemuhle, Epson, Moab, etc…. Now I have a sample Epson Legacy Paper Sample Pack ( which has 3 sheets of 4 différents legacy papers), Hahnemuhle Glossy FineArt, Epson Signature Worthy Sample Pack ( has 2 papers of each of 7 différents papers), Hahnemuhle Sample Pack Digital FineArt Collection, Natural Line ( includes 2 sheets of each of them 4 différents papers), Hahnemuhle as the last one, but Matte FineArt Smooth ( 2 sheets of each of 5 différents papers). I bought also a Moab Sample box ( 2 sheets of each of 11 varieties of papers). I am trying these papers sample and see what I like the most with my wildlife photo. As my friend told me to do, is to choose two photos of birds and a furry animal and print the same photos on each papers. Then make a catalogue with them and see what I like the most. And if one day I decide to sell a print, I will have something that I can show the client and see what he or she prefer. We all have different opinion and preference.
During Christmas, someone wanted to buy two of my photos ( printed 16 X 20 In ) of one of the monuments I took few years ago in Washington DC, during the Cherry Blossom blooms. I did not know what kind of paper to use since the two photos are a landscape. I asked an advice from a photo shop that they make print and also they sell photos. I showed them the photos and they advice me to print them on Epson Exhibition Fiber Paper. I did and the client loved the prints.
Bottom line, use some samples, you can buy them from B& H and their assistants are very knowledgeable with all kins of prints and they can help you to choose from the big variety of sample that they have.
i forget also to mention that I got also the Moab Artist card package to print cards. I am still in the process of learning.
Good luck with your printer and make use of it. It gives a lot of joy to see our photos printed, than just on a screen.
