cups-pdf package has the following package script with a faulty assumption that if cupsd is running that /var/run/cupsd.pid does exist.  Like this:

# First install : create the printer if cupsd is running
if [ "$1" -eq "1" -a -f "/var/run/cupsd.pid" ]
then

    if [ -d /proc/$(cat /var/run/cupsd.pid) ]
    then
        /usr/sbin/lpadmin -p Cups-PDF -v cups-pdf:/ -m CUPS-PDF.ppd -E || :
    fi
fi

It could have used pidof or pgrep instead.  On Fedora 16 a test for an existence of /var/run/cupsd.pid always fails; this file is simply NOT created.

A workaround - after you installed the package run, as root,

 lpadmin -p Cups-PDF -v cups-pdf:/ -m CUPS-PDF.ppd -E

yourself.  It appears that there is no way to create this queue with a help of system-config-printer although it will show up once created as above.
