Digital BW, The Print

http://www.inkjetart.com/hp/B9180/

This review seems convincing (as much as any review could be).
Inkjetart has been totally reliable in the past in their evaluations
of paper, ink, and printers.  

Check their  observations about carbon and comparison to 2400. I've
not been blown away by 2400 B&W work that I've seen...it's OK,
evidently easier for some to work with than 2200, but prints aren't
better on matte paper than 2200 used well. It's about time to retire
my 2200, time marches on...

Anybody here use HP B9180 ? What papers? Is your experience in line
with inkjetart's highly detailed review?
