  Title   Printer browsing in net-print/cups-1.6
  Author  Andreas K. Huettel <dilfridge@g.o>
  Posted 2013-06-30
  Revision                  1

net-print/cups-1.6 no longer supports automatic remote
printers or implicit classes via the CUPS, LDAP, or SLP
protocols, i.e. "network browsing".

The browsing functionality can be restored by running
cups-browsed from net-print/cups-filters as a separate
daemon (just add its init script to your default runlevel).
By default cups-browsed uses the net-print/cups-1.5 browse
protocol, but it can also utilize zeroconf (if the zeroconf
use flag is set). See /etc/cups/cups-browsed.conf for
configuration.

Of course, directly specifying the location of your
printers in the cups interface works as well.

Seems to me that you could try as root:
