I agree wholeheartedly. But that's too bad because the 20ps has a nice image
forming mechanism -- the image sharpness, at 600x600, is pretty impressive.
And the PostSript RIP they ship with it is decent.

So far, after 48 hours, it is not any better than with the EPSON, the
Dupont, the Oci or the AGFA. I am going to complain about that to HP
tomorrow cause I would have expected that it would perform better, since it
comes from HP and is supposedly 'approved' for this printer.

I hope to get my hands on one of those soon. But, in the meantime, I'm stuck
with this HP 20ps.
Now, in general, the fact that a paper may take a long time to dry (more
than 24 hrs, for instance) would not make a printer/media/ink combo
unacceptable or unusable. As long as one could still make good profiles out
of it. Alas, in the case of the 20ps, for the life of me, using either PO4
or PM4, I cannot find any way to nail that ugly yellowish-greenish cast. No
matter what I do.
If I measure the target (after 48hrs) with the Spectrocam, I will get less
of that yellow cast, but it still a bitch to edit. And if I only have a
DTP41uv at my disposal, it seems that no amount of profile editing will ever
succeed in ridding the profile of its yellow cast!
