OK, "Listen hostname" is entirely dependent on DNS to return the right
values. Since there are a lot of variables (besides the order which cupsd
is started) for when network facilities are available, you really need to
have the hostname and any addresses listed in /etc/hosts to make that work
reliably.

Moreover, if you have a dynamic address you should not be using "Listen
hostname" at all. Instead, stick to "Listen *:631" or just "Port 631" - the
default ACL will limit access to the local subnet(s), and you can tweak
those to prevent access from outside addresses.
