The prints are just fine. ABW is nice and black, though not much different than my old Canon 6300. Resolution is where P800 steps ahead.
Its main problem, IMO, is that the overall design is 'up past its bedtime' – Epson has offered too many iterations of this 17" printer without rethinking basics, so that single-sheet loading and the user interface belong to the dark ages of inkjet printing.
A minor problem that bugs me: Epson is too 'proprietary' about its own papers, and you can't always combine the loading method, paper profile, and paper thickness you might want when using other fine art papers. For example, if you want to use HPR with the recommended VFA media setting, you must always use the single-sheet loading method; even when you use 220 or 276 weight sheets of HPR you have to run them through the clumsy single-sheet-feed mechanism, because VFA won't appear as a possible setting for the auto-sheet feeder.
