Sorry to be thick... I don't see where foomatic is involved. Samba 
spools the job to cups which runs pstops and then sends the job along to 
the printer. Is foomatic inside of cups?  Is that just saying use -oraw?

I can munge pstops.c  at about line 600  with this

       else if ((!strncmp(line,"%%EOF",5)) || (!strcmp(line, "\004") && 
len == 1) )
       {
         /*do nothing with EOF or ctrl-D */
       }
       else if (strncmp(line, "%%Pages:", 8) != 0)
         pswrite(line, len, stdout);

which eliminates the first EOF and ctrl-D but does not seem to strip out 
the color info as i want it to - this despite the presence of

%%BeginFeature: *XRXColor BW

  <<
     /DeviceRenderingInfo currentpagedevice 1 index get 1 dict copy
    dup /VirtualColorDevice <<
                 /Type 1
                 /ColorTransform /Gray
      >> put
  >> setpagedevice
%%EndFeature

in the ps file

Is it not possible to strip the color info from this input by directing 
the output through pstops?

I hope I'm not hammering a screw...
