Abstract

A system and method for efficiently utilizing the output devices of a computer system to perform output functions. The output devices are capable of bidirectional communication and are capable of generating information pertaining to static and dynamic attributes of the respective output devices. Responsive to the additional information pertaining to the static and dynamic attributes of the output devices, particular ones of the output devices are allocated to effectuate particular ones of the output functions.

Claims

1. A method for managing operation of a set of bidirectional output devices coupled to a processing device having an end user interface and to a database storage device, the set of output devices adapted to receive command signals for performing predetermined operations and to generate signals indicative of the condition of selected attributes thereof, said method comprising the steps of:

a) querying the output devices through the processing device to receive therefrom signals indicative of the current status of their selected static and dynamic attributes;

b) storing the value of each of the signals indicative of the selected attributes of the output devices in the database storage device each time the output devices are queried;

c) accessing selected ones of the signal values stored during said step of storing; and

d) managing operation of the set of output devices in response to the current static and dynamic attributes thereof.

2. The method of claim 1 wherein said querying step further comprises periodically querying the set of output devices to determine signals indicative of the current status of their selected static and dynamic attributes.

3. The method of claim 1 wherein the set of output devices comprise a plurality of print resources and said step of managing operation comprises allocating utilization of the print resources to effectuate print jobs in accordance with the current status of the selected static and dynamic attributes of the output devices.

4. The method of claim 3 wherein said step of allocating the utilization of the print resources is dependent in part upon the input entered by way of the end user interface.

5. The method of claim 3 wherein said step of allocating the utilization of the print resources is dependent in part upon the print jobs to be effectuated by the print resources.

6. The method of claim 3 wherein allocation of the print resources to effectuate the print jobs optimizes the utilization of the print resources according to a selected criteria.

7. The method of claim 3 wherein said step of managing the operation of the selected print resources further comprises the step of providing selected ones of the signals indicative of the static and dynamic attributes of the print resources to the end user interface in human perceptible form.

8. The method of claim 1 wherein said step of querying the output devices occurs in response to an input entered by way of the end user interface.

9. The method of claim 8 wherein said step of managing the operation of the selected output devices comprises the step of providing the selected ones of the values accessed during said step of accessing to the end user interface in human perceptible form.

10. In a computer-controlled system having a host computer, an end user interface, and a set of bidirectional output devices, each output device adapted to receive command signals for performing predetermined operations and to generate signals indicative of the condition of selected static and dynamic attributes thereof, a combination with the host computer and end user interface of an apparatus for managing operation of the set of output devices, said apparatus comprising:

a) querying means for requesting signals indicative of the current status of all selected static and dynamic attributes of the output devices therefrom;

b) storage means for storing the values of the signals indicative of the current status of all selected static and dynamic attributes of each output device therein each time the output devices are queried;

c) accessing means for accessing selected ones of the values stored in said storage means responsive to an input request therefor entered by way of the end user interface; and

d) circuit means responsive to the current status of all selected static and dynamic attributes of each output device for managing the operation of the set of output devices in response to the current attributes thereof.

11. The apparatus of claim 10 wherein said querying means are adapted to periodically query the values of the signals indicative of at least the dynamic attributes of each output device and said storage means stores the signals resulting from each periodic query therein.

12. The apparatus of claim 10 whereto said accessing means includes a first computer server coupled to the end user interface and to said storage means, said first computer server being adapted to receive the input entered through the end user interface and to initiate access to the values stored in said storage means.

13. The apparatus of claim 12 wherein said circuit means comprises a second computer server forming a scheduler responsively coupled to said first computer server.
