Digital BW, The Print

Ok, today I made profiles using Create ICC-RGB for the other papers I  am 
interested in and everything seemed to go fine.
 
But now I have a new, weird problem.
 
Suddenly I am unable to make prints using the new QTR profiles I made  
today, as well as those I made earlier and have printed successfully  with in 
the past. The 1400 printer seems to be working fine, I get a perfect  nozzle 
check and prints I make using any non QTR profile comes out fine. But the  
prints I make using the custom QTR profiles come looking almost like a couple 
of  the nozzles are not putting any ink down at all, almost a solarized 
look. When I  print out a grayscale, there is no smooth transition from black to 
white, the  print looks like a zebra's back in varying shades of gray.
 
I am assuming this is most likely due to some incorrect setting I have  
made in Photoshop in the print dialogue? I have checked over and over and  as 
far as I can see, I've got all the same settings for printing that I did  
before I started having this problem earlier today.
 
Any ideas what might be wrong? The profiles I made using QTR for Premier  
Art b/w and Moab Entrada worked fine up until I started having this problem  
today and now they are generating these messed up prints as well.

In general I've found that the same PS curves are close enough to be  
linearized with all matte papers. So, you generally just have to print a  21-step 
with the curve on a new paper, read the test strip, and drop it and  the 
curve (on the special rgb file) into Create ICC.

Note that here I'm  talking about the monotone inksets. The complex curves 
to control colors on,  for example, UT7, often do not create even color 
tones on different paper  coatings.
