In your .convs file use:

     application/postscript application/vnd.cups-postscript 0 
/path/to/your/script

and then in your script write your output into a temp file.  After
you have processed the file, run pstops with the temp file as
input, e.g.:

     TEMPFILE="$TMPDIR/scriptname.$1"
     ... do stuff to send output to $TEMPFILE
     /usr/lib/cups/filter/pstops "$1" "$2" "$3" "$4" "$5" "$TEMPFILE"
     rm -f "$TEMPFILE"
