Abstract
A print controller and associated methods of performing recovery processes responsive to a redrive event (i.e., print setting changes/hardware errors) are disclosed. A print controller in one embodiment comprises a job storage system that receives and stores print jobs from host systems, and a print data path from the job storage system to one or more print engines. The print data path includes components operable to process print jobs for imaging on the print engine. The print controller further comprises a redrive system that detects a redrive event, and identifies the print job interrupted by the redrive event. The redrive system also identifies a target page of the identified print job from which to restart the print job, and purges the identified print job from the print data path (along with other print jobs). The redrive system then reschedules the identified print job for processing followed by other eligible jobs.
