That are non continuous tone printer, they dither the image and usual
the resolution is not very high.

They are designed for billboard printing not for fine art photographic
printing.

Durst Lambda is an full colour laser printer, which is able to render
images on photographic paper (including real B&W silver based paper).

The difference between Durst Lambda and inkjet printer is the better
quality of the Durst. The Lambda as continuous tone device is able to
produce highest resolution prints with exceptional smooth colour and
grey gradients, like one is used from conventional prints on
photographic paper.

The advantage of the Durst Lambda is the ability to produce prints in
a size difficult to realize with conventional enlargers. Of course it
is also an high quality output for digital data, but there the quality
of the digital data is the limiting factor. Not very many scanner are
able to produce equivalent quality scans and only very beefy computers
are able to handle the large file sizes.

I meant the minilab, which are capable tools, but often luck the
attention and care of their operators, owners.

Inkjets are non continuous tone devices, they need to rasterize the
image, working with sometimes 6 different inks. Pretty complex
calculations have to done to produce the impression of an continuous
tone image. My impression is that the printer driver are "intelligent"
adapting the printing to the source image, making it a bit difficult
to
calibrate the output.

Better printer driver are able to use embedded colour profiles, this
helps a lot. 

I think part of the success I had with digital mini labs, is owed to
the fact that those mini labs were able to use embedded profiles.

I printed a chart and let it measure in a company for printer inks. It
showed that not all of the three colours had the same maximum density.
This did gave me two options. Calibrating for the least dense colour
avoided colour cast but let the images look less contrasty, pale.
Trying to get maximum density produced sometimes noticeable colour
casts, which were difficult to compensate.


Traditional print material might not be perfect, but is IMHO better,
has better colours, deeper blacks, better contrast, better gloss.

You can talk to the operator, telling him how you like your prints.
Making one test print and then an corrected final print. It's more
costly but less than a pro photo printer.

I don't print all my images only those few I consider worth to be
enlarged. It helps that I most use slide film (which was very
difficult to print until digital processing was mature enough).

I don't own an colour inkjet printer. But I could use different
samples and I heard about the experience other people made. 

The discussion about colour casts in "archiveable" Eps*n prints is not
my invention but discussed in the net.

No problem, don't want to argue with

N*k*n D1 has _serious_ colour problems, bad rendering of skin tones
etc.

Depends on the test chart

D1 has worse colours and resolution is lower than much cheaper Olympus
consumer DC.

EOS1 RS, Robot, Kodak high speed digital cameras (used for crash
tests,
much faster, much more expensive), all film cameras who are able to
produce at least 25 fps. This is a special feature not normally needed
in photography.

Robot cameras are relatively inexpensive, but which consumer needs
15 fps?

Add the price of the device and it is no longer that economic.

Interesting device if you need or want your photo instantly.

I suspect it was the operator because the machine was new and setup by
the Fuji tech. The operator enlarged slides on this machine probably
for the first time.

For slides they had to make some changes, I expect they forgot to
readjust focus.

Of course, contrast can be more easily altered with the help of an
computer. Agfa pioneered this with "Digiprint", more than 10 years
ago, resolution was a little bit low then. Today I suspect most slide
enlargements are made with similar but improved technology
(resolution, it's no longer possible to detect grid patterns). Slide
enlargement from from big labs, photo finisher are surprisingly good
today (at moderate prices), much better than they used to be.
