Have you tried with the ICM files upstream provides? You should
download them with the 'getweb' script:
# getweb 3175
Then, if nothing changes, please also try moving the ICM files from the
foo2zjs folder to the foo2qpdl one:
# mv /usr/share/foo2zjs/icm/samclp3* /usr/share/foo2qpdl/icm/
In the current Debian package (version 20090908dfsg-4), the 'getweb'
script puts all ICM files into /usr/share/foo2zjs/icm/. The same script
From the Ubuntu package, however, splits them in the correct folder,
something I am integrating in Debian as well.

That is good to know. Do you have any Samsung's ICM that you can try
with foo2zjs? However, I am not sure Samsung's ICM will work...

This should be OK, according to upstream INSTALL file:

GHOSTSCRIPT BUGS
----------------
* ghostscript 8.64 is broken w.r.t. color. Don't use!
* Well Tempered Screening (WTS) works with ghostscript 8.54 thru 8.70+.
So if you want BEST COLORS, you'll have to install gs 8.54 or better
if you don't have it.
[...]
* Ghostscript before 8.55 has a problem with ICM files and 64-bit gcc.
It causes a segfault with km2430_2.icm. So don't select that one.

I have never used such files (I own only an HP Color LaserJet 1500L, now
broken), but you should simply copy the upstream QPDL files from
foo2zjs/crd/qpdl/* into /usr/share/foo2qpdl/crd/.
NB, these files were removed from the Debian package because their
license is unclear, thus we can not distribute them.
Obviously, you can also try to use the QPDL files from Samsung's
proprietary Linux driver.
Finally, there is a new updated package, with a lot of improvements and
more synchronized with the Ubuntu package (but it still misses the split
for files downloaded via the 'getweb' script):

If you can try this new package, please let me know first if it works
and then if anything changes.
Thx, bye,
