Ghostscript.
Adobe's postscript printer
You can write the eps manually (define some useful macros and the actual
generation becomes easy)
Probably XSLT would do the job as well.
It really depends on what you want to do with the eps files and whether
it is important to use eps at every step.
If you have some control over the client side it gets easier.
Otherwise you need to send data to the server and let the server create
a new eps.
Where do the eps files get used?

I've already said what I need to do, pick a premade draw, and allow
the user to change the blanks to color, like in a paint app for kids,
and then export this to an eps, that simple is the idea.
The queries must be received by a server ( a custom app?), or I'm
missing something...
You said, a lot of tools to create outputs, to eps? can you name one?
thanks

This sounds like a server side issue.
There are lots of tools to create output on a server.
Why are people changing the colors. Does this get done for each print
or is the color changed once and requested from a server.
It might save a lot of time if you actually described what you want
to do in enough detail so we can get to the right solution in the
next 4 or 5 weeks.

hi Ron,
I already have it done this way. A postscript printer in the server,
and it works like a charm. But the problem is how to receive a lot
of queries for printing with an automated app...any idea?
thanks

Can you not just use a postscript printer under windows to create
the file?
If you download the Adobe generic PostScript driver, set the output
to file and to be eps rather than PostScript and you should be able
to print your Flash to eps.

Ok, I'll try to put it simple.
I have researched about the eps, I opened it, changed it, and I
see where are the paremeters I need with a few problems(like
identify each shape to apply different color), but if you want,
forget the eps input.
The point is:
1 - I Have a swf with a drawing inside and 2,3,4 colors divided in
movieclips by color.
2 - I need to open this swf with my app, let the user change the
color of each mc (at this point, everything is fine)
3 - give the user an eps with the result.
end of workflow.
simple uh? :P

I am having trouble figuring out the flow.
What does the Flash application actually do? If the drawings
already exist on the server and have to end up on the server,...
What does Flash do with the EPS file? Why EPS at all? How do the
EPS files get created.
What do you want to do with the resulting files?
Have you edited an eps file with a text editor to see how they
are constructed? They can include vectors and raster images.
Depending on the program used to create the EPS, it can be full
of crap and unused macros which make them hard to pick apart if
that is what you want to do.
You can certainly create eps files by tracking the user inputs
and writing the PostScript to a file. It is a bit like SVG
without the XML. You can create your own macros to make the
process easier - which is where all of the crap comes from in an
EPS file created by MS-Word (to pick on one vendor unfairly).
Make a "Hello World" document and save it. It will be a lot
longer than 11 characters but you will find "Hello World" in
there somewhere.
In the early days of DOS, I wrote a little short PostScript file
that created fractal images if you sent it to a Postscript
Printer and let it run all night. Looking back I must not have
had a life then, I guess - the kids were small and we were to
tired to go out.

Ok, sounds good, but I don't see clearly how to convert my
already drawn eps/whatever into commands so can rewrite a svg an
then save it.
I can make instructions for writing the svg, but I have the
drawings pre made.

You can send an XML file of drawing instructions to the server
and use XSLT to do anything that you want.
a) You can convert it to SVG or EPS.
b) You can convert it to your own vector format
c) You can hold onto it as an XML and redraw it in your Flash
program later
d) You can convert it to a raster image
e) You can do all of the above and more.
SVG is the most flexible format since it is both an XML file
that can be transformed using XSLT and a recognized vector
drawing format that can be edited using drawing programs. It is
also relatively easy to construct by tracking the user activity
on the Flash side(move, draw, draw, draw,move, draw...)
Check the Batik site and open an SVG file in a text editor to
see what is inside.

What I need is to import the drawing, that's why I choose eps
(but the only real need is that it must be vectorial), Not
really to export the image created by the user, but recreate
it on the server side, based on a few parameters.
I can live without the drawing part.
PDF would be a possibility, but can I export from swf 2 pdf??
about FOP, It could be useful but how I load the eps/whatever
icon and apply some changes (color, scale or so)?
thanks

Have you looked at SVG as an alternative? You may be able

What about PDF.
Have a look at Apache's FOP as a server tool for converting
input to various output formats.
Let me know what you think of these. There may be more ways
to skin this cat.
How are the drawings made? If you are capturing the user's
interactions, SVG might be pretty easy since it sort of
mimics the steps that the user does (start here, draw to
here, draw to this point, draw to next point, etc. finish
here; move to here, draw to here, etc.) so you may be able to
create the SVG by just transforming what you are already
doing on the screen.
The Batik package or Adobe SVG lets you work with SVG
drawings. What do you want to do with the output- what is
magical about EPS for you?

I generate the content of the swf on the client app, let's
say a free drawing, then I want to "print it" to the *server
printer* (?).
The point is...I need an eps from a generated content with
origin in the client machine.
You was talking about "many free printer drivers", can you
point me to some of them?
thanks

How are the swf's generated in the first place? Instead of
doing
something->swf->eps
you can do:
something->swf
something->eps
