Something like the following should do it:
-------------------------------------------------------------------
#! /bin/bash
# debug info in /var/log/cups/error_log
set -x
# set inputfile to where the input comes from
inputfile="-"
test "$6" && inputfile="$6"
# forward input to file
if cat $inputfile >/tmp/myfilter.out
then echo 'INFO:' 1>&2
      exit 0
fi
echo 'ERROR: failed to forward input to /tmp/myfilter.out' 1>&2
exit 1
-------------------------------------------------------------------

Install this script as /usr/lib/cups/filter/myfilter
with the same owner, group and permissions as the
other filters (usually "rwxr-xr-x root root").
