Sorry for posting the summary this late, here it is anyway:-

A trivial example of what you want to do:
#!/bin/csh -f
cat /full/path/to/prefixfile
cat

There is some info in the Anserbook Rel 1 Issue 3
System and Network Administration ( Book )
12. Maintaining Printers and Print Servers ( Chapter )
12.5 Output Filters ( Section )
Output Filter Specifications ( Subsection )

This was described in the Sys & Net Admin manual for 4.1, but was
omitted for 4.1.1. Here is a shell script we used for an if= filter.
It illustrates the calling conventions.
#!/bin/sh
#
# if filter for lpr
# filter [-c] -wwidth -llength -iindent -n login -h host acc_file
# files: 0 --> input data 1 --> printer 2 --> lf file
# return: 0: okay 1: reprint 2: discard
#
PATH=/usr/5bin:/usr/bin:/usr/ucb:/usr/local/bin
Z=`basename $0`
#
# parse options
#
for i in $*
do
arg=`expr $1 : '..\(.*\)'`
case $1 in
-c) shift ;;
-w*) form=$arg; shift;;
-l*) length=$arg; shift;;
-i*) indent=$arg; shift;;
-n) shift; login=$1; shift;;
-h) shift; host=$1; shift;;
*) acc=$1;;
esac
done
echo '\033%-12345X@PJL ENTER LANGUAGE=PostScript'
cat
echo '\033%-12345X\c'
exit 0
#!/end
