Digital BW, The Print

I currently print b&w with an epson 1200 using MIS VM (epson driver) 
inks with awesome results (Paul, latest curves are GREAT!). I've been 
printing a lot lately on 13x19 EAM but find that i am fighting the 
size. I end up with approx 12x16 from my 6x7 negs. I like the idea of 
printing on 16x20 -- so i guess that leaves the epson 3000.  So can i 
get similar printing quality as my 1200? Do i need to use piezo 
software? What about paper, is EAM available in 16x20?

Thanks for any advice.

Cheers,
Peter
