Abstract
Abstract A printing system for distributing print requests submitted by one or more clients includes a server that receives the print requests, generates a print job from one or more print requests, and extracts attributes of the print job. A database contains attributes of the logical printers and physical printers associated with the logical printers, the queues of a network and the attributes of the print job received from the clients. A database query is used to filter the attributes extracted from a print job against the attributes of the physical printers associated with the logical printer to which the print job was sent to determine whether the print job is printable by at least one of the associated physical printers. A queue stores print jobs that are determined to be acceptable. Each printer is capable of notifying the server when it is idle. A second database query, based on the attributes of an available physical printer, is used to filter against the attributes of the available printer against the attributes of the printable jobs in the associated queue, to determine which available jobs are printable on the available printer. One of the determined printable jobs is then output to the available physical printer.
