Abstract: A print controller, methods, and software are disclosed. A print controller of the invention includes applications, a parameter manager, and a notification system. The applications register with parameter manager those parameters for which they want to be notified when a change occurs. As part of the registration, the applications designate a callback identifier (CID) for each of the parameters, where an individual CID may be associated with a single parameter or a plurality of related parameters. Responsive to receiving an indication of changes to one or more of the parameters, the notification system identifies the applications registered to be notified of changes to the parameters, and identifies the CIDs associated with the parameters that have changed. The notification system then transmits one or more notification messages, including the identified CIDs for the changed parameters, to each application that is registered.

Abstract: A printer system and method of managing the printer system. Printer sub-systems can register indicating system parameter affecting or, affected by, each. The printer is monitored for change requests to system parameters and, printer sub-systems are selectively notified of a requested parameter changes. Notified printer sub-systems respond indicating a time to apply each parameter change. Unless changes can be applied immediately, a change notification is displayed, requesting operator intervention and indicating a time for the intervention.

Abstract: A method defines an execution of a business service by an electronic service. The method includes steps of: defining at least one canonical data schema containing data type specifications in an electronic services registry; defining at least one electronic service interface specification in the electronic services registry, the electronic service interface specification defining messages being received and sent by a service, the message definitions referring to one or more of the data type specifications, and also containing addressing and encoding information for the delivery and receiving of messages to and from the service; and defining business service specifications in a business services registry, referring in the specification to an electronic service specification.

Abstract: A method for providing a predictive out status of a printer is disclosed. The method comprises determining a media requirement of a job for the printer, determining that the proper amount of the media is within the printer, and determining if the job can be printed at the printer based upon the media requirement and the proper amount of media within the printer. In a second aspect, a method in a printer network is disclosed. The method comprises determining if a job can be printed in a default printer. The method further comprises querying all other printers in the network to determine if the job can be printed, if the job can not be printed at the default printer. The method then allows for printing the job at one of the other printers if the job can be printed at the one printer. In a system and method in accordance with the present invention, a predictive message is posted that the printer does not have sufficient paper to complete the task.

Abstract: A printer system stores a trace of a printer job in storage that is either local or accessible to the printer system. A remotely implemented tool accesses the stored printer job trace. The tool includes a graphical interface that displays the printer commands in the printer job trace in a human readable format. The commands may be displayed in a first window of the interface. In one embodiment, the interface includes a second window where details of a command selected or highlighted in the first window are displayed. The tool may be implemented as a secure web browser that requires password verification to access the printer job trace. The tool may include the ability to replace confidential print data with generic or non-confidential data. The tool might further be able to display text that is embedded in a printer job trace command in ASCII and EBCDIC format.
