Abstract

An effective method for securing the release of the transmission, rendering, and outputting of an imaging/print job at an imaging device, for imaging/print jobs that originate in traditional print/spooling subsystems include the following steps. A print job header is associated with an imaging/print job to form a headed imaging/print job. A secured release input (that may be input at a secured release input apparatus of the client host device) is associated with the print job header by including a secured release indicative command/code in the print job header. The headed imaging/print job is divided into data packets. Initial data packet(s) are transmitted to the imaging device. It is determined whether the secured release indicative command/code is present in the initial data packet(s). Acceptance of subsequent data packets of the headed imaging/print job are prevented if the secured release indicative command/code is present in the initial data packet(s). When a secured release input is received on a secured release input apparatus of the imaging device, subsequent data packets of the headed imaging/print job are accepted.
