Abstract
The present invention has an object to avoid an inconvenience of potentially not being able to use a department managing function. In a system environment to which the department managing function is to be applied, if two-way communication between a printer and a client computer is anticipated to be inoperable, the processing is switched over so as not to carry out an authentication processing using two-way communication.
Claims18
A printing system which requests execution of authentication processing by transmitting entered authentication information to a printer which performs authentication processing on the basis of identification information, comprising:
- determining means which determines whether or not a result of authentication processing is available from the printer;
- and
- issuing means which, when said determining means determines authentication processing is unavailable, discontinues a request for execution of authentication processing, and issues a printing job including the entered authentication information and printing data to the printer.
An information processor which requests execution of authentication processing by transmitting entered authentication information to a printer which performs authentication processing on the basis of identification information, comprising:
- determining means which determines whether or not a result of authentication processing is available from the printer;
- and
- issuing means which, when said determining means determines authentication processing is unavailable, discontinues a request for execution of authentication processing, and issues a printing job including the entered authentication information and printing data to the printer.
An authenticating method for performing authentication processing on the basis of identification information when using a printer, comprising:
- a determining step of determining whether or not result of authentication processing is available from the printer;
- and
- an issuing step, when unavailability of authentication processing is determined in said determining step, of discontinuing a request for execution of authentication processing and issuing a printing job including entered authentication information and printing data to the printer.
A program executed in a system performing authentication processing on the basis of identification information when using a printer, which causes a computer to execute:
- a determining step of determining whether or not a result of authentication processing is available from the printer;
- and
- an issuing step, when unavailability of authentication processing is determined in said determining step, of discontinuing a request for execution of authentication processing and issuing a printing job including entered authentication information and printing data to the printer.
An information processor which requests execution of authentication processing by transmitting entered authentication information to an authenticating unit which performs authentication processing on the basis of identification information, comprising:
- a memory storing a control program including a determining step of determining whether or not a result of authentication processing is available from the authentication unit;
- and a discontinuing step of discontinuing requesting execution of an authentication processing when unavailability of authentication processing is determined;
- and
- a processor which executes said control program stored in said memory.
An authenticating method of requesting execution of authentication processing by transmitting entered authentication information to an authentication unit which performs authentication processing on the basis of identification information, comprising:
- a determining step of determining whether or not a result of authentication processing is available from the authentication unit;
- and
- a controlling step, when unavailability of authentication processing is determined in said determining step, of discontinuing requesting execution of authentication processing.
