Yes do something like this, as filterscript at /usr/lib/cups/filter

---8<---- file: pswrite
#! /bin/bash

# enable "set -x" for debug info in /var/log/cups/error_log
#set -x

# set inputfile to where the input comes from
inputfile="-"
[ -n "$6" ] && inputfile="$6"

# output PostScript level 1 (for PostScript level 2 use -dLanguageLevel=2)
gs -q -dBATCH -dPARANOIDSAFER -dNOPAUSE -sDEVICE=pswrite -dLanguageLevel=1 -sOutputFile=-
$inputfile
---8<--------

and change 

the following line in /etc/cups/mime.convs from 
application/pdf         application/postscript  33      pdftops

to
application/pdf         application/postscript  33      pswrite

but!

is it really necessary?
What is the reason to do it?
