Hi Elly.
If you are able to name the pdf's to your needs, it's very simple ;-)
Create a script under /usr/lib/cups/filter, name it to whatever you want, 
let's say 'printertopdf'.

Set FileDevice yes in your cupsd.conf
Create a new print queue with DeviceURI file:/dev/null
lpadmin -p printqueuename -E -P /path/to/postscript.ppd.gz -v file:/dev/null

Do not start cups at this moment. If it runs, stop it ;)
Edit /etc/cups/printers.conf an in the newly created queue and insert 
between <Printer printqueuename> and </Printer>:
Filter application/pdf 0 printertopdf

In the script use (taken from dvitops):

#!/bin/sh

if test "$#" -lt "5"; then
        echo "ERROR: Number of arguments ($#) is wrong" 1>&2
        exit 1
fi

if test "$#" -gt "6"; then
        echo "ERROR: Number of arguments ($#) is wrong" 1>&2
        exit 1
fi

# Log the command line
echo dvitops: $@  1>&2

# Get the last parameter (which is the filename if present)
eval filename="\${$#}"

case "$filename" in
    printer1.pdf)
        lp -d printer1 $filename
    ;;
esac

You now got your file which must be printed ;)
Depending on your filenames you are now able to take the right printer to 
print the pdf ;)
