Digital BW, The Print

I'm just guessing, but I'm pretty sure this is just an update of the
old Epson Stylus RIP with the ability to drive the 2100/2200. It's
always been a bit of a dog. Mostly, it was for design shops to proof
layouts with, as it had some postscript capability. No jaggy type or
EPS elements.
It was awful to attempt to use it as a true CMYK RIP, it was in fact
what we first tried to use years ago for better control of quad ink
channels in CMYK. Unfortunately it refers back to Epsons RGB screening
(nice dither) and will regenerate K by it's own rules. The only
control it afforded over the RGB driver was that untill it began to
replace CMY with K, CMY channels were left unmuxed if you had the
settings right. It was also slow and a memory hog, was buggy, and
created large spool files.
Color management with it is also odd since it is supposedly a CMYK
RIP, but behaves as an RGB device.
If you need to output postscript you might want it, and possibly there
are features for B&W with the 2200, but I always thought it was a dog.
