       notifier - cups notification interface


       notifier recipient [ user-data ]


       The  CUPS  notifier  interface provides a standard method for adding support for new event
       notification methods to CUPS.  Each notifier delivers one or  more  IPP  events  from  the
       standard input to the specified recipient.

       Notifiers  MUST  read  IPP  messages  from  the  standard  input  using  the  ippNew() and
       ippReadFile() functions and exit on error.  Notifiers  are  encouraged  to  exit  after  a
       suitable  period  of  inactivity, however they may exit after reading the first message or
       stay running until an error is seen.  Notifiers inherit the environment and  can  use  the
       logging mechanism documented in filter(7).
