You can alter /etc/cuspd.conf to deny access to anyone you don't want
printing from your subnet
There also is a way to make the cups server silent so it does not
broadcast its presence. I don't
remember where but you use to have to turn it on if you wanted it. It
should be in the CUPS manual somewhere
below is a link with inforamtion on the cupsd.conf file. Be sure to make
a copy before you play with it.
