   I just sent my ScreenDump.c to the moderator of mod.amiga.sources.
It's not quite what you want but it'll give you something to play with.
It dumps the highest screen or window and allows the user to choose
various image and output options.  You can go as low level as you want
with the output options, all the way to setting each DumpRPort parameter
youself.  

   You can specify exactly how many dots you want the output to be.
Unfortunately, 1 to 1 will probably not give you the results you
have in mind.  The aspect ratio of the screen pixels is not the same
as the aspect of the printer dots, and a circle on the screen will
be an oval on the printout.

   As you probably know, a ratio such as 1 to 2 will result in each
dot on the printer being duplicated rather than leaving a space
between dots.

   A program like SeeILBM.c (on our IFF disk) will load an IFF pic
into an Intuition screen/window (borderless backdrop).  ScreenDump
can be used in conjunction with this to print out your ILBM's
in any size you want.  

   If you don't want the picture displayed, write a program that combines
EA's ShowILBM.c with Screendump.c.  Pull out their DisplayPic stuff
(and the related de-allocations) and instead create a dummy RastPort
structure that describes and points to their bitmap structure.
Give DumpRPort a pointer to this dummy RastPort.
