Digital BW, The Print

That's what I've been thinking about for awhile, and possibly using the additonal channels for gloss enhancer and split toning hues like red and blue and yellow. Putting thermal inks like that in a Piezzo printer sounds a little scary.

John, It would be nice. Perfect automatic head maintenance. Heads that 
can be replaced at an affordable price when needed.
But what driver will do the partitioning, linearisation, color toning 
and in the end the printing?
It is very unlikely that curves in PS and the HP driver (in Paul Roark's 
style) will deliver any quality improvement.
Even with a RIP like the Wasatch SoftRip like I used for a 9000 quad you 
still have no control on the 3 or 4 K inks separately, it still is a 
black box to the user. QTR doesn't have HP printer support and even 
GutenPrint is way behind with its Designjet drivers.

The B9180, Z3100 and Z3200 do a very good job in B&W printing, right out 
of the box. Better in my opinion than the Epson and Canon out of the box 
solutions. Beyond that you have to look for Epson hardware, QTR and 
K6-7-8 solutions with or without HP inks. That is the result of the 
front runner's role of Epson in the past,  the influence this list had 
and the R&D efforts of maybe 10 people in the last 10 years  to get 
better digital B&W printing. It will be difficult to repeat that again 
for the other printer brands. As I understand it also will be difficult 
for the x900 Epson printers.  If I recall it correctly the Bowhaus shop 
tried something for the Canons but I have not seen any sign of it in 
practice. Jon Cone and Canons is another vague memory.
