You need to explain more.
...and what is a "hungry rip"?

If these B&W "greyscale" image files are from a camera, do you
understand that you have no need to shoot RAW unless you are processing
from color originals?

There is a whole bunch of information missing from your question. You
seem to be making things unnecessarily complicated.

in the headline is written SCANNER!
hungry rip means i need more than 900dpi for getting the best
ditthering.
i hope these information are enough for such a simple question.

Two things here;
I have been using scanners of various types for quite a few years now,
I managed to get to 63 and I still have a pulse.
"hungry rip" means nothing to me.

What is the size of the image you are scanning?
What size do you intend to have this final image?


Since you are scanning you don't need a RAW converter. You are going to
need decent image editing software and Photoshop should do the job just
fine.
Don't try to reach your final print size from the scanner. You are
going to be better off using dedicated resizing software such as
OnOne's "Perfect Resize 7" this was formerly "Genuine Fractals". If you
don't have the cash handy, they have a trial version. Take a look at
their videos, you might learn something.

Then you need to get an understanding of dpi requirements for scanning
photographs and negatives/transparencies vs requirements for printing.
Here is one starting point:

If you want answers, try to be a little clearer with your questions.
Somebody here might have an answer to a question they understand.

BTW: here is one of my scans of an old family image. The original scan
for this image was 7571x6000 @ 600ppi for a file size of 32.6MB.
resized for web viewing to 960x761 @ 300ppi (I should have dropped this
to 72ppi as for web viewing this make no difference at all) with a file
size of 233 KB

joe.dobbs <bernha...@gmail.com> was inspired to say
Joe

I don't know what scanner you are using, but I suspect that Photoshop
has more sophisticated resizing tools than the scanner's interpolation
('dithering').

Scan at the native resolution of the scanner (to a Tif file) and do all
resizing in PS. Some people advise one step resizing, others recommend
several. I can't comment there.

Hope that helps

Mike
