Method of maintaining security in a common output means and system for maintaining security

摘要

A common output unit such as a print server maintains security when an output request unit, serving as a client, sends a job to be processed to the output unit. The output unit accepts and puts the job in queue. The output unit then creates a collation key that is sent back to the output request unit, which stores the collation key in a storage medium. The output unit searches the storage medium for the collation key and processes the queued job corresponding to the collation key. The print server includes a locked stacker and an ordinary stacker to minimize the output waiting time of the print job.
