[cups] cups-2.3.0: 127.0.0.1:631/printers/ is incomplete (no printers shown)

Hi,
 I use cups from Gentoo linux but the page http://127.0.0.1:631/printers/ does not list any printers. I think this is after upgrade 

# emerge -pv cups

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R    ] net-print/cups-2.3.0::gentoo  USE="X dbus pam ssl threads usb -acl -debug -kerberos -lprng-compat (-selinux) -static-libs -systemd -xinetd -zeroconf" ABI_X86="32 (64) (-x32)" 0 KiB

  I think the previous versions worked fine.

  Looking at the source code of the page I see the page in incomplete:
