Sorry for the late reply! I'm quite satisfied with both printers, especially because of the new deeper blacks. The differences between P9000 and P20000 is what you'd expect in regards to the extra green and orange in the P9000, just like with the previous generation. The extra grey ink in the P20000 hardly matters to me. (I don't do that much b/w anyway) Slightly lesser gloss differential in some highlights, but I will spray my glossy prints anyway to get rid of it all. I'd much rather have a green ink personally. (and how about a gloss optimizer this century?
)
I haven't timed it, but my impression is that the P20000 is very fast. I also love the ease of mounting wide rolls: Resting the roll on the supports on top of the printer while attaching the end pieces. Then just sliding everything in place.
Some negative points on the P20000:
- I've seen some weird horizontal "banding" problems in black areas approximately 3 inches from the end of sheets, on matte media, printing on 1200dpi. Sort of like what happens when you run out of ink in the middle of a print, you spend 2 minutes changing a cartridge and the printer resumes, but you end up with a cm of uneven shadow areas.. This does not happen with 2400dpi, so I've been using that. I haven't spoken to Epson or researched this issue much further, because the extra time used for 2400dpi is mostly fine with me. I'll look more into it though.
- When loading sheets/rolls (which is very smooth/foolproof with this printer) the printer takes a minute getting ready, which is not very entertaining, so I'm back at the PC. But after hitting "Print" I have to return to the printer to confirm the media setting. Hitting OK for every damn sheet. This is not a big issue though..
- I'm 360ppi for the other Epsons, but the P20000 wants 300ppi. So I have to prepare separate print files. Again, not a big issue.
I think that both printers delivers excellent quality (but so did the previous few generations imho). And that's what's important to me, I can deal with a few nuissances.
