Digital BW, The Print

I've searched the archives with no hits, so...

I was wondering if anyone here uses the Epson 4000 for B&W only 
printing.  I'd love to be able to print 16x20.  MIS makes mention of 
support for UT7 and 4000, but doesn't go into any details, and Paul 
Roark's site doesn't mention the 4000 at all.

Are there other alternative for printing sizes larger than the Epson 
2200 can handle, but not as big as the 7600?
