Abstract
Printing systems and methods are described in which the priorities of print jobs are programmable. A scheduler component oversees print job management and scheduling, and works in concert with components called prioritizers, to provide for ease of programming and customization. In at least some embodiments, an interface to the system is provided to allow prioritizers to be programmed and inserted to customize the behavior of the scheduler according to different print job properties. In at least some embodiments, the system utilizes a model for the relative prioritization of print queues in the system to enforce a fair to balancing of system resources between print queues. In at least some embodiments, the system can independently schedule the rendering and printing operations when printing a job and can use a heuristic known as 'starvation risk' to help ensure that throttling rendering in the system does not result in device starvation.
