A system and method support load balancing for print jobs on a peer-to-peer network. The system incorporates a job forwarding query manager and a printer controller selector in a printer controller. The query manager detects a condition for forwarding a print job and generates queries to alternative printer controllers for available logical printers. The responses contain logical printer characteristics and load measurements for logical printers that are capable of processing and printing the forwarded print job. The printer controller selector determines which logical printer has the characteristics necessary to print the print job and the least load. The attributes of the print job are merged with the logical printer attributes of the logical printer at the querying controller to ensure correcting printing of the forwarded print job by the logical printer to which the print job is forwarded. If no logical printer has the characteristics required for printing a print job, the printer controller selector determines whether the missing characteristic can be downloaded to the alternative printer controller to which the logical printer is coupled. If the characteristic can be downloaded, the printer controller selector sends the characteristic to the alternative printer controller for installation on the logical printer and forwards the print job to the alternative printer controller upon confirmation that the characteristic has been successfully installed.

The present invention provides a method and an apparatus for responding to changes in measurement of a system load in a spread spectrum communication system. Using a load control algorithm, for example, the spread spectrum communication system may handle sudden changes or variations, such as spikes or steps in system load measurements for an uplink and / or a downlink between a mobile unit and an access network. The load control algorithm determines whether a sudden variation of a measured system load is generated by a source not under a power control or is caused by a variation of a spread spectrum communication system load. A load control measure may be selectively applied to adjust one or more parameters associated with the system load. That is, an increase of a first new measurement value may be limited to a given maximum increment for one sampling time period of a plurality of sampling time periods in response to a spike in the system load or a desired response to a sudden increase of the system load may be delayed by a given maximum number of measurement samples. By allowing a limited increase, the response of the spread spectrum communication system to sudden changes of a system load may be controlled such that some blocking may occur but dropping of calls may be avoided. In this manner, the load control algorithm may avoid unnecessary dropping of calls.
