Abstract

A central print system in which print jobs are directed to a particular print resource based on a set of print job attributes specified by an end user at the time the print job is submitted. The central print system provides intent-based printing which allows the end user to specify the end result of the printing operation rather than initially selecting a print resource. A print job manager processes the print job using the end user selected print job processing attributes to select the appropriate print resource from a group of networked print resources. An attribute registers a set of job processing attributes for each print resource servicing a single print queue and provides a list of available print job attributes to each client computer on the network from which an end user specifies particular job attributes to define a desired end result for a print job. The attribute manager periodically updates the job processing attribute list as print resources are added to or deleted from the network. The central print system may include one or more add-on modules accessible by the print job manager which provide additional functionality to the print system not available in or required to be provided by a print resource.

Claims

1. A method of selecting a job processing resource for processing a print job in a network having a host computer, a print server, a set of network job processing resources coupled to the print server, and a central print system for processing a print job as a function of user selected job processing attributes, the method comprising the steps of:

registering with the central print system one or more sets of job processing attributes, each set of job processing attributes associated with a different one of one or more job processing resources;

providing a list of available job processing attributes to a user, the user selecting one or more job processing attributes from the list of available job processing attributes;

submitting a print job together with the selected job processing attributes to a print queue;

selecting a job processing resource as a function of the selected job processing attributes; and

transmitting the print job from the print queue to the selected printer.

2. The method of claim 1 wherein at least one of the selected job processing attributes is satisfied by one or more add-on modules provided by the central print system.

3. The method of claim 1 wherein the step of selecting job processing attributes includes the step of prioritizing one or more of the selected job processing attributes.

4. The method of claim 1 wherein the step of selecting a job processing resource includes the step of prioritizing one or more of the selected job processing attributes in accordance with a predetermined set of rules.

5. The method of claim 1 wherein the central print system includes a job manager, and wherein the step of selecting a job processing resource includes the step of adding one or more predetermined job processing attributes to the selected job processing attributes prior to selecting the job processing resource.

6. The method of claim 1 wherein the central print system includes an attribute manager, and further including the step of updating the list of job processing attributes in accordance with a set of registered job processing attributes.

7. The method of claim 6 wherein the list of job processing attributes is updated at the time of each print job request.

8. A central print system for processing a print job as a function of user selected job processing attributes in a network having a host computer, a print server and a set of network job processing resources coupled to the print server, the central print system comprising:

a print queue for receiving print jobs submitted by a host computer;

a job manager for processing print jobs received from the print queue in accordance with the user selected job processing attributes; and

an attribute manager for registering one or more sets of job processing attributes, each set of job processing attributes associated with a different one of one or more job processing resources.

9. The central print system as in claim 8 wherein the job processing resources include one or more network printers.

10. The central print system as in claim 8 wherein the job manager selects a job processing resource in accordance with at least one of the selected job processing attributes to further process the print job.

11. The central print system as in claim 8 wherein the job processing resources include at least one add-on module providing predetermined job processing functionality accessible by the job manager.

12. The central print system as in claim 11 wherein the job manager selects at least one add-on module in accordance with the selected job processing attributes for processing at least a portion of the print job prior to selection of a job processing resource.

13. The central print system as in claim 8 wherein:

the job processing resources include at least one printer; and

the job manager is adapted for prioritizing the selected job processing job attributes in accordance with a set of predetermined rules and for selecting a printer for further print job processing in accordance with at least one of the selected job processing attributes as a function of the priority assigned to the job processing attributes.

14. The central print system as in claim 8 wherein the attribute manager includes storage means for storing and maintaining a database comprising the sets of job processing attributes.

15. The central print system as in claim 14 wherein the attribute manager is adapted for updating the job processing attribute database as job processing resources are added or deleted from the network.

16. The central print system as in claim 8 wherein the attribute manager provides a list of all available job processing attributes to the host computer.

17. The central print system as in claim 16 wherein the list of all available job processing attributes is updated whenever the central print system is initialized.

18. The central print system as in claim 16 wherein the list of all available job processing attributes is updated each time a user initiates submission of a print job.

19. The central print system as in claim 8 wherein the job manager is adapted to provide a matrix of all available job processing attributes to insure user selected job processing attributes are consistent with the job processing capabilities of the network job processing resources.

20. An article of manufacture comprising a program storage medium having computer readable program code means embodied therein for causing the selection of a print resource in a computer network having a host computer, a print server, a set of network print resources coupled to the print server, and a central print system for processing a print job as a function of user selected job processing attributes, in accordance with one or more user specified job processing attributes, the computer readable program code means in the article of manufacture including:

computer readable program code means for causing a computer to register with the central print system one or more sets of job processing attributes, each set of job processing attributes associated with a different one of one or more print resources;

computer readable program code means for causing a computer to provide a list of available job processing attributes associated with one or more print resources available on the computer network;

computer readable program code means for causing the computer to select a print resource from the one or more print resources available on the computer network as a function of at least one of one or more user specified job processing attributes selected form the list of available job processing attributes; and

computer readable program code means for causing the computer to transmit a print job associated with the specified job processing attributes from a print queue to the selected print resource.
