Digital BW, The Print

The basic problem with the 2200 is metamerism, which means that 
black and white prints have DIFFERENT color casts under different 
light sources.  For instance, the same print might look greenish 
under daylight and pinkish under "daylight fluorescents"

This is caused by pigmented inks Epson uses for color stability 
having uneven spectral response curves, especially the yellow ink, 
so it CANNOT be fixed with Photoshop curves or "gray balancing" 
tools, etc, because those can't control the distribution and ratios 
of individual inks.   You have 3 options:

1.  The Image Print RIP is your best bet but it's around $400.  It 
has a special driver which allows it to use a different mix of the 
inks (essentially it takes advantage of the fact that the black and 
light blacks are really sepia, so it can get "yellow" that way and 
not have to use so much actual yellow ink.  See my scans:

Epson had a RIP like that but they discontinued it.

2.  Black Only.  Tell the printer to only use the black ink - it's a 
setting in the driver.  I've done extensive tests with this method 
and even have a (current) gallery show with some BO prints (on 
tinted paper).   BUT -  I did an experiment that involved visual 
acuity and it made one thing really clear : there was an 
overwhelming inverse correlation between closeup visual acuity and 
tolerance for BO prints.   People with poor close vision like them; 
people with good close vision find the dots and coareseness in the 
midtones objectionable.   I suggest if you do BO printing, only use 
it for large prints that will be viewed from far away.  I also 
suggest that if you don't see the dots, have your eyeglass 
prescription updated.

3.  3rd party quadtone/hextone/septone inks.  I have no experience 
with this on the 2200, but I wouldn't advise it if you also want to 
routinely do color printing with the same printer because switching 
between two inksets is a major hassle.

Or you can as I do and send your BW digital files out to be printed 
on photographic paper at a pro lab.
