Abstract

Disclosed is an object model hierarchy for use in a Graphical User Interface (GUI) for a Palladium print management system. The standard Palladium object model provides a containment relationship between servers and the objects the servers manage; these objects include printers, queues, and jobs as well as other print objects. The GUI object model maintains the server containment relationships established in the Palladium model. Additional containment relationships are defined for the GUI to give the user effective means of monitoring all objects in the printing system.

Object Hierarchy for Palladium Print Management Graphical Interface

      Disclosed is an object model hierarchy for use in a Graphical
User Interface (GUI) for a Palladium print management system.  The
standard Palladium object model provides a containment relationship
between servers and the objects the servers manage; these objects
include printers, queues, and jobs as well as other print objects.
The GUI object model maintains the server containment relationships
established in the Palladium model.  Additional containment
relationships are defined for the GUI to give the user effective
means of monitoring  all objects in the printing system.

      Palladium is a model of a distributed print system defined
by MIT's Project Athena and detailed in the ISO Document Printing
Application (DPA) 10175-1 standard and the IEEE/POSIX System
Administration Interface/Printing P1387.4 standard.  The Palladium
model provides all components of an advanced heterogeneous
distributed print system.

      Two types of print servers are defined in the Palladium model,
supervisors and spoolers.  Supervisors manage printer devices while
spoolers manage the flow of jobs through the print system.  All other
print objects are contained in one or both of these types of servers,
establishing a parent/child relationship between servers and their
contained objects.

      The supervisor contains physical printers, which represent the
printer device, as well as other print resources, such as media and
auxiliary sheets.  The GUI model maintains this hierarchy so that
when the user views a supervisor, all contained objects are provided.

      The spooler contains logical printers which represent one or
more printer devices to the user who submits print jobs.  The spooler
also contai...
