In an SNMP-based network management system, an agent within the system maintains a quantity of memory which serves as a 'lock table.' The lock table is a set of object identifiers (OID's) relating to objects associated with the agent. When a manager on the network requests a particular object associated with the agent, the agent retains the OID of the object in the lock table. If another manager simultaneously wishes to set an object associated with the agent, the OID of the proposed object is compared to any OID currently in the lock table, and if the proposed object intersects with one of the objects in the lock table, access to the object is denied. The method permits locking of specific objects, while leaving other objects associated with the same device available to others.

Locking mechanism for network-managed agents in a digital printing system

An electronic printing system prevents printing failures and interruptions associated with the inability of an image generation subsystem to generate a page image in digital form in real-time by reviewing the page contents prior to submission to the image generation subsystem. The quantity, size, geometry and location of objects on a page are analyzed to generate an internal intermediate description of the page. A determination is made if sufficient resources exist to perform real-time imaging. If real-time imaging cannot be performed, the page will be automatically simplified before the job containing the page is submitted for printing.
