Use a System V-style interface script instead of a PPD file.   
Something along the lines of (untested!):

#! /bin/bash
PATH=/bin:/usr/bin:/usr/sbin:/sbin export PATH # paranoia
job="$1"
user="$2"
title="$3"
copies="$4" # the only thing we actually use
options="$5"
shift; shift; shift; shift; shift
f=""
if [ $# = 0 ]; then
     # save stdin to a temp file so we can print it properly
     f="`mktemp /tmp/pjbXXXXXXXX`" || exit 1
     cat >"$f"
     set -- "$f" # so now it's a script argument
fi
# if you need to printf(1) escape sequences to set draft mode, etc.,  
do so here
: ${copies:=1}
for pf in "$@"; do # for each file argument
     while [ $copies -gt 0 ]; do # for each requested copy, if people  
print with "lp -nCOPIES ..."
	cat "$pf"
	printf "\f"
	let copies--
     done
done
if ! [ "x$f" = x ]; then
     # clean up our temporary file from above
     rm "$f"
fi
exit 0

You specify this the same way you do a standard PPD file to lpadmin;  
I don't know how that works with the web interface, though.
