I've been printing wide-format (Canon and older Epson) for years, but I'm now in a situation where I'll need to move a few times in the next several years (maybe twice a year). Anything larger than a 17" printer becomes a massive pain to move with, so an iPF6300 or an Epson 7900 are out. I'm used to roll paper, and like to print 16x24 (thereby 17x22 sheets are a pain). The only truly modern 17" printer I seem to be seeing on the market is the Epson 4900 (the 3880 is a last-generation inkset and heads, and lacks roll feed, and the iPF 5100 is similarly last generation, although with a good roll feed).
I'm a little worried by all the x900 clogging posts, although I live in a more humid part of the country. I print fine-art landscape, for myself and for some gallery sales... Volume is certainly low by print shop standards (although probably not unusual for an artist/teacher)!
I like the 4900's tray and paper handling, because I'm assuming that I can use it as a "convenience" printer for word processing documents and the like in addition to its primary role as a photo printer. Without the automatic path switching, that would be an unbelievable pain...
What else should I look at (if anything)? Is there likely to be some printer coming out that will meet my needs for a serious art printer with roll feed that is relatively movable by car??
