I noticed a recent flier from Midwest announced a new 17" Epson 4000 printer that takes ultrachrome inks. It sounded interesting, so I thought that I would check into it. Here's Epson's announcement:
This sounds like a good product for those who can't afford or don't want the footprint of the 7600, yet can still make reasonably large prints. It also accepts the 220 ml ink cartridges, which cuts down on printing costs. It's an eight color printer, including both the matt and glossy black inks.
(By the way, I have no affiliation with Epson!)
