I have just installed an Epson P800 and the profiles for the papers I plan to use (Hahnemuehle). Images are processed with Capture One Pro. The problem I found is that in the Media Type menu option, there is no way to select the papers from Hahnemuehle, only those corresponding to Epson papers appear....I do not know how important this is or affects the final result. I have selected the icc profile corresponding to the Epson P800+ Photo Rag paper in "Printe Profile" option....currently I am running the trial version in order to see if I will use CO directly or Qimage Ultimate instead.
Augustin,
It has been my experience that Printer manufacturers rarely if ever show another brand of paper. The paper company like (Hahnemuehle, Red River, Lexjet, etc. ) make profiles for their papers and your printer. When they make the profiles, they have to select a paper listed by Epson to make the target. They will specify when you download the profile, which paper selection to use from the P800 list.
Look through their instruction sheets.
