Abstract

A combination of physical and logical components of an apparatus to establish a persistent connection over a network with a source that is provided with or part of a job service. The components extract a job instruction embodied in a first communication that is received from the source over the persistent connection, without the apparatus having provided a request for the first communication. Based on the job instruction, the components send a request to the job service for job data when the job service is able to process job data for a corresponding job, without the apparatus polling the job service or waiting for the job service to receive the corresponding job.

Claims

1. An apparatus comprising:

a combination of physical and logical components to;

establish a persistent connection over a network with a messaging service that is provided with or as part of a job service, wherein communication over the persistent connection occurs under a first communication protocol in which communication requests are not required;

receive a notification over the persistent connection at a first client in the apparatus, wherein a job instruction is encoded in the notification;

extract the job instruction from the notification;

send the extracted job instruction from the first client to a server in the apparatus under a second communication protocol requiring request-based communications;

forward the extracted job instruction from the server to a second client in the apparatus;

under the second communication protocol, send a request from the second client to the job service for job data identified in the extracted job instruction;

receive the job data from the job service at the second client; and

process the received job data to produce an output.

2. The apparatus of claim 1, wherein the first communication protocol provides for the apparatus to receive the notification without having first requested the notification, and wherein the job data is provided under a second communication protocol which provides for client and server type communications.

3. The apparatus of claim 2, wherein the first communication protocol is XMPP (Extensible Messaging and Presence Protocol) and the second communication protocol is HTTP (Hypertext Transport Protocol).

4. The apparatus of claim 1, wherein the job instruction includes a Uniform Resource Locator (URL).

5. The apparatus of claim 1, wherein the persistent connection is established across a firewall that protects the apparatus.

6. The apparatus of claim 1, wherein the apparatus is a printer.

7. The apparatus of claim 1, wherein the job instruction further includes parameter settings, such as color printing, duplex printing, stapling, multiple copies and collating, among others.

8. The apparatus of claim 1, wherein the notification further includes identifying the apparatus.

9. The apparatus of claim 8, wherein the notification is wrapped in the first communication protocol when extracted, and wherein the request is wrapped in the second communication protocol when sent.

10. The apparatus of claim 1, wherein the communication over the persistent connection under a first communication protocol pass over a first data channel, and wherein the request for job data under the second data protocol pass over a second data channel different from the first data channel.

11. A method for operating an apparatus to process job data over a network, the method being implemented by one or more processors of the apparatus and comprising:

establishing a persistent connection over the network with a messaging service that is provided with or as part of a job service, wherein communication over the persistent connection occurs under a first communication protocol in which communication requests are not required;

receiving a notification over the persistent connection at a first client in the apparatus, wherein a job instruction is encoded in the notification;

extracting the job instruction from the notification;

sending the extracted job instruction from the first client to a server in the apparatus under a second communication protocol requiring request-based communications;

forwarding the extracted job instruction from the server to a second client in the apparatus;

under the second communication protocol, sending a request from the second client to the job service for job data identified in the extracted job instruction;

receiving the job data from the job service at the second client; and

processing the received job data to produce an output.

12. The method of claim 11, wherein the first communication protocol provides for receiving the notification without having requested the notification, and wherein the job data is provided under a second communication protocol which provides for client and server type communications.

13. The method of claim 12, wherein the first communication protocol is XMPP (Extensible Messaging and Presence Protocol) and the second communication protocol is HTTP (Hypertext Transport Protocol).

14. The method of claim 11, wherein the job instruction includes a Uniform Resource Locator (URL).

15. The method of claim 11, wherein the persistent connection is established across a firewall that protects the apparatus.

16. The method of claim 11, wherein the apparatus is a printer.

17. The method of claim 11, wherein the job instruction further includes parameter settings, such as color printing, duplex printing, stapling, multiple copies and collating, among others.

18. The method of claim 11, wherein the notification further includes identifying the apparatus.

19. The method of claim 18, wherein the notification is wrapped in the first communication protocol when extracted, and wherein the request is wrapped in the second communication protocol when sent.

20. A system comprising:

a job service;

a printer, wherein the printer is to;

establish a persistent connection over a network with a messaging service that is provided with or part of the job service, wherein communication over the persistent connection occurs under a first communication protocol in which communication requests are not required by the printer;

receive a notification over the persistent connection at a first client in the printer, wherein a job instruction is encoded in the notification;

extract the job instruction from the notification;

send the extracted job instruction from the first client to a server in the printer under a second communication protocol requiring request-based communications;

forward the extracted job instruction from the server to a second client in the printer;

under the second communication protocol, send a request from the second client to the job service for job data identified in the extracted job instruction;

receive the job data from the job service at the second client; and

process the received job data to produce an output.

21. The system of claim 20, wherein the first communication protocol provides for the printer to receive the notification without having first requested the notification, and wherein the job data is provided under a second communication protocol which provides for client and server type communications.
