1. A computer-based method for carrying out a negotiation concerning set of actions to execute a print job performed by selected ones of a plurality of participants, wherein at least one of the plurality of participants encapsulates a constraint solver in a service, comprising: defining processing instructions in a memory of the system for carrying out the negotiation using the service encapsulating the constraint solver to facilitate printing via a processor; and executing the processing instructions, via the processor, to carry out the negotiation with the service encapsulating the constraint solver; wherein said executing the processing instructions for carrying out the negotiation with the service encapsulating the constraint solver further comprises: (A) establishing encapsulation input in the memory that includes: (a) a mapping between one or more of a price, a size, and a delivery date of print-job parameters of the service and corresponding variables of the constraint solver, (b) a translation between negotiation statements on the one or more of a price, a size, and a delivery date of the print-job parameters of the service and domain constraints imposed on the corresponding variables of the constraint solver, and (c) a set of semantic constraints of the service on variables of the constraint solver; (B) constructing a graph in the memory for negotiating the set of actions to be performed, wherein each action corresponds to one or more invocation patterns, each node of the graph defining a negotiation context that has associated therewith a constraint store with at least a set of domain constraints stored therein; (C) propagating constraints defined by the set of semantic constraints and the set of domain constraints associated with nodes of the graph to other participants in the negotiation as domain constraints augment the set of semantic constraints during the negotiation utilizing a protocol defined by one or more primitives that are instantiated by the one or more invocation patterns; and (D) executing one or more actions based at least in part upon the interdependencies between the one or more invocation patterns, the one or more actions facilitate printing of at least one print job, each print job creates at least one hard copy document based at least in part upon the processing instructions.
