Thanks for many many posts on this thread and another thread about R3880. R3000, R2000, Pro-10
Finally I ordered R3880, after back and forth between R2000, R3000, Pro-10, and R3880.
I dropped Pro-10 since it only prints 13x19, while other three Epsons can print up to 37" or 44".
I dropped R2000 since it is said R3000 and R3880 work better with B$W.
It then left R3000 and R3880. R3000 can handle roll paper, but it seems not really convenient, and pre-cut the roll paper is not avoidable. If so, I can do the same with R3880.
I also order the first roll paper. The premium Luster Archival, 16x100. It's not 17" wide, but the price is nearly half of 17" roll. I thought about 10" and 13" roll too, but I have a concern on the ink clog or ink residue on the side if print full bleed, borderless
I don't have anything worth to print 17" yet. 13" may be as wide as I'd go. I'll print ~13" on 16", with border.
After my first roll, I'll probably try Moab Slickrock Metallic.
Anything I should know, before I open and plug my R3880?
