Can PFP produce neutral B&W prints with either of these
printers?
PFP doesn't control metamerism, thats the printers job. So printers that lack two grays, and which use color inks to form light grays, have metamerism issues in B&W prints. Simple as that. PrintFIX PRO can help you get better B&W from them, but only for one light source, metamerism will still be an issue. Not so for the Epson 2400 and 3800 printers, however. They produce metamerism-resistant grayscale and tinted prints with PFP profiles.
Is the lack of a second gray a killer for producing neutral
B&W with PFP? Is metamerism going to be a significant problem?
Yup, for any printer that mixes its light grays from color inks, instead of mostly from a light gray ink, that will be an issue for B&W prints. I was supposed to get a Canon PRO9500 in advance of release for testing, but it never materialized, so I can't comment on how it makes its light grays, I can only extrapolate from other models. Any way you cut it, the PRO9500 should improve on the terrible metamerism of the PRO9000, which was so bad that even a color image with lots of neutrals in it was problematic.
