A method and system for monitoring performance of a multifunction printer (MFP) throughout the lifetime of the MFP. The MFP may include a task run-time controller to collect performance information from the MFP and to transmit the performance information to a receiver such as a host, an MFP front panel, or a website. The task run-time controller may include a high resolution timer to collect task execution times or idle time for tasks running on the MFP. The task run-time controller may also receive internal task scheduling policy alterations based on an analysis of the performance information.

1. A method for monitoring internal task performance of a multifunction printer (MFP), comprising: enabling a monitoring capability at one of (a) run-time of the MFP and (b) boot-up of the MFP;collecting performance information of the MFP over a period of time, wherein collecting the performance inf

1. A method for monitoring internal task performance of a multifunction printer (MFP), comprising: enabling a monitoring capability at one of (a) run-time of the MFP and (b) boot-up of the MFP;collecting performance information of the MFP over a period of time, wherein collecting the performance information comprises: remotely generating a printer job language (PJL) job;transmitting the remotely generated PJL job to the MFP using a communication medium; andparsing the PJL job using a PJL parser in the MFP to determine at least one requested action; andsending the performance information to a receiver. 2. The method of claim 1, wherein the receiver is at least one of (a) a host, (b) an MFP front panel, (c) a printout from the MFP, (d) a report sent to a fax machine, and (e) a website. 3. The method of claim 1, further comprising printing the performance information using a printer. 4. The method of claim 1, wherein collecting the performance information includes: remotely collecting the performance information using a communication medium from a location different from where the MFP is located. 5. The method of claim 1, wherein collecting the performance information includes: collecting the performance information on-site at a location substantially the same as where the MFP is located. 6. The method of claim 1, further comprising: periodically generating the performance information; andtransmitting the periodically generated performance information to at least one of (a) the host, (b) the MFP front panel, (c) the printout from the MFP, (d) the report sent to the fax machine, and (e) the website. 7. The method of claim 6, wherein the performance information is automatically generated. 8. The method of claim 1, further comprising: tailoring the performance information to include individual task information and task group information. 9. The method of claim 1, further comprising: permanently storing the performance information in a non-volatile storage medium. 10. The method of claim 1, further comprising: temporarily storing the performance information in at least one of (a) a non-volatile storage medium and (b) a volatile storage medium. 11. The method of claim 1, wherein the at least one requested action indicates a request for the performance information, and wherein collecting the performance information further comprises: processing the at least one requested action using a task run-time controller of the MFP; andtransmitting the performance information via the communication medium responsive to the request. 12. The method of claim 1, wherein the monitoring capability is enabled by default. 13. A method for monitoring performance of a multifunction printer (MFP), comprising: enabling a monitoring capability of the MFP;remotely generating a printer job language (PJL) job from a location different from where the MFP is located, wherein the PJL job indicates a request for performance information;transmitting the remotely generated PJL job to the MFP;parsing the PJL job using a PJL parser in the MFP to extract the request;collecting the performance information using a task run-time controller of the MFP responsive to the parsing; andtransmitting the collected performance information to at least one of (a) a host, (b) an MFP front panel, (c) a printout from the MFP, (d) a report sent to a fax machine, and (e) a website. 14. The method of claim 13, further comprising: enabling the monitoring capability at one of (a) run-time of the MFP and (b) boot-up of the MFP. 15. The method of claim 13, further comprising: enabling the monitoring capability by default. 16. The method of claim 13, further comprising: periodically generating the performance information; andautomatically transmitting the periodically generated performance information to at least one of (a) the host, (b) the MFP front panel, (c) the printout from the MFP, (d) the report sent to the fax machine, and (e) the website. 17. A multifunction printer (MFP), comprising: at least one processor;a communication medium layer;a plurality of task groups, each task group being associated with one of printing, scanning, copying, faxing, and networking operations;a Printer Job Language (PJL) parser coupled to the communication medium layer, the PJL parser to receive at least one PJL job via a communication medium, the PJL parser configured to parse an alteration of an internal task scheduling policy, the alteration included in the PJL job;a task run-time controller coupled to the PJL parser, the task run-time controller configured to receive and process the alteration, to transmit performance information to a host coupled to the communication medium, and to save the performance information and the alteration, the task run-time controller comprising: a high resolution timer including at least one watch dog timer configured to monitor a status of a plurality of tasks running on the at least one processor;a task tuner configured to apply the alteration of the internal task scheduling policy at one of (a) run-time of the MFP and (b) boot-up of the MFP; anda task manager configured to perform book-keeping operations of the performance information and the alteration. 18. The MFP of claim 17, wherein the alteration included in the PJL job indicates an adjustment of task scheduling levels associated with at least one of the printing, scanning, copying, faxing, and networking task groups. 19. The MFP of claim 17, wherein the communication medium layer comprises User Datagram Protocol (UDP) messaging firmware configured to transmit data grams including at least one of (a) the performance information and (b) the alteration of the internal task scheduling policy between the MFP and the host.
