Very helpful and practical review of what sounds like an excellent printer. I have just a few general questions given that I've never used any of the Epson "pro" printers (nor anyone else's):
(1) If I read you correctly, the 4900 has noticeable image improvement over the 3880, correct? Did you find this more/less true depending upon whether the image was in color or b/w?
(2) It seems that Epson doesn't sell papers in, say, 16x20 size. Does this mean that one must use roll paper? I so, can you instruct the printer to cut at 16x20 or must this be done after the image has printed at 17x22?
(3) I'm just curious why Epson doesn't offer 16x20 or 11x14 sizes.
