Digital BW, The Print

About 6 months ago I posted some quetions here about black and white 
printing for the 2200 on a PC.  At that time there were 3 main 
approaches:

1.  Use the stock Epson inks and drivers and live with the 
metamerism.

2.  Use black-ink-only.   No metamerism but very dotty and contrasty.

3. Use a RIP, since the RIPs use a different dithering algorithm 
that de-emphasizes the inks that are the biggest metamerism culprits 
such as the yellow.   At that time the IP, Epson, and PowerRIP RIPs 
were the main candidates.   People mailed me test images for the IP 
and EPson RIPs which I posted on my website and confirmed that they 
produced relatively neutral (a little bit sepia), metamerism-free 
prints with good tonal range. 

Rumours abounded that septone ink cartridges would be available Any 
Day Now for the 2200 but at that time none existed.


I've been mostly away from the forum since then so __MY QUESTION__ 
is whether there have been any important NEW developments for BW 
printing on a 2200 for PC users since then.
