    This is a risk for hosts running Cups in an untrusted LAN;
certainly not at home. I don't know for you guys, but it would take me
some config work on my internet box to map some incoming port to port
631 of the host running Cups; and why would I do this for? In addition
this requires to have a private WAN IP address for the box.

    But, in an untrusted LAN the risk may be made even bigger by Cups
design: if a host is connected to two networks, its Cups server allows
by default to hop from one LAN to the other for printing.
