Image forming system, computer-readable recording medium storing driver program, and image forming method for remote job execution

摘要

If a logged-in user to a host terminal device succeeds in user authentication via a directory server device, a user-manager server device transmits a job ticket and authorization information corresponding to the logged-in user to the host terminal device. The host terminal device receives the job ticket and the authorization information, generates a job execution instruction responsive to the authorization information, and transmits the generated job execution instruction to an image forming apparatus along with the job ticket. When the job execution instruction is received from the host terminal device, the image forming apparatus executes a job specified by the job execution instruction if the job ticket received along with the job execution instruction is determined to be valid.
