A method, apparatus, and system for outputting a locked print job by a printing device connected to a client device over a network. The method includes transmitting, by the client device, a request to print the locked print job, which includes print data that is prohibited from being printed until authentication information is entered into the printing device. The printing device receives the request to print the locked print job. The locked print job and the authentication information are stored in a memory. A job ticket that provides the client device access to manage the locked print job stored in the memory is generated. The job ticket is transmitted to, and received by, the client device. The locked print job is output when the authentication information is entered into the printing device or the locked print job is remotely released by the client device using the job ticket.
