System for maintaining a cache of printer-readable prioritized content
First Claim
1. A system for prioritizing a cache of print jobs associated with at least one print driver, the system comprising:
- a workstation having a processing unit;
at least one print driver having a processing unit, the workstation and the at least one print driver configured for interfacing via a network, andwherein the processing unit of the workstation has a set of programmable instructions configured for;
implementing a print job request for a document; and
determining whether a document key identifier associated with the document exists, wherein if no document key identifier exists, creating the document key identifier associated with the document;
transmitting the document key identifier to the at least one print driver; and
wherein the processing unit of the at least one print driver has a set of programmable instructions configured for;
receiving the document key identifier from the workstation;
determining whether a printer-readable format for the document associated with the document key identifier is stored in at least one of at least two caches configured for interfacing with the workstation and with the at least one print driver via the network;
assigning a prioritization identifier to the printer-readable format if the printer-readable format for the document associated with the document key identifier is stored in the at least one of the at least two caches;
wherein the prioritization identifier is selected from the group consisting of a timestamp, a document length or a document topic;
wherein if the prioritization identifier is the timestamp an additional timestamp is assigned for each print job request;
wherein if the prioritization identifier is the document length, one cache of the at least two caches is a document length cache and the printer-readable format for the document associated with the document key identifier is stored in the document length cache; and
wherein if the prioritization identifier is the document topic, one cache of the at least two caches is a document importance cache and the printer-readable format for the document associated with the document key identifier is stored in the document importance cache.

Abstract
A system for prioritizing a cache of print jobs associated with at least one print driver includes a workstation having a processing unit and at least one print driver having a processing unit, that interface via a network. The workstation implements a print job request for a document and determines whether a document key identifier associated with the document exists. If not, a key is created. If a printer-readable format for a document associated with the key identifier is stored in or is pre-existing in one of at least two caches, the print driver assigns a prioritization identifier to the format. The system retrieves the printer-readable format from the cache to produce a print job output. Since the cache stores the document in printer-readable format, overall printing time is reduced. The format may be moved from one cache to another depending upon priority. The corresponding method is also disclosed.
