Keep the answers coming.
My initial review will consist of downloading, installing over the
release candidate on my Mac (10.4.x) (hope I don't hit problems),
adding whatever settings are recommended by people reading this,
and printing profile charts- I specifically want to see if the
driver can survive "out of the box" use by someone who is NOT a
rocket scientist. I believe that for open source to succeed
software must obey the prevalent standards of usability in addition
to providing good functionality.
I'll be very interested in your results.
A pointer to the developers - I believe RIPs usually have a way of
ingesting linearisation readings and adjusting ink curves and ink
limitation settings - this makes life with color management on
random media MUCH easier.
Gutenprint per se can do this (at least for the primaries -- CMYK),
but the problem is that we have no way to get this curve information
past CUPS. Apparently there's a way in OS X to write a driver that
presents a user interface around or after CUPS (I don't know the
architecture); we'd have to do that in order to be able to offer the
more advanced options, and we don't have anyone who can do this.
Note that in RGB mode the release candidate driver survived the review
process quite well, so please don't accuse me of scheduling a military
tribunal for open source crimes ;)

I really need to understand this red issue on the R2400 better. I'm
also surprised about the report of long pauses between passes -- I'm
quite certain that this issue (if that's actually what you're seeing)
was fixed in -rc3. It might also simply be that the driver is rather
slow. However, I'm seeing a lot of results of poor driver performance
that sound excessive -- e. g. a report that the driver performed
poorly on a dual 2.0 GHz G5 -- that we need to investigate.
