(5) CUPS Filters (Till)

- Latest CUPS Filters and mobile print status (Till)
  - https://blueprints.launchpad.net/ubuntu/+spec/
    client-1305-printing-stack-with-mobile-in-mind

- CUPS Filters v1.0.45 released (Till)
  - cups-browsed does not require any more that avahi-daemon has to be
    started before cups-browsed
    - cups-browsed keeps running when avahi-daemon is stopped and
      restarted
    - cups-browsed always picks up avahi-daemon in these cases and
      recovers discovering the Bonjour broadcasts of remote printers
    - cups-browsed is absolutely robust against on-demand use of
      avahi-daemon

  - cups-browsed can be made automatically terminating if it is not
    needed any more
    - in auto-shutdown mode it terminates a given timeout (default 30
      sec) after there is no cups-browsed-generated local print queue
      any more (= no cups-browsed-discovered remote printer any more)
    - auto-shutdown mode can be activated by command line option, signal
      to the daemon, or env variable and it can also be set so that
      auto-termination only happens when avahi-daemon is stopped

- Currently working on making cupsd robust against stopping and starting
  avahi-daemon (Till)
