Abstract
An image forming apparatus is provided that includes mechanisms for registering strings, extracting text information from received job data, determining a job availability of the received job data based on a comparison of the extracted text information with the registered strings, associating a result of the determination of job availability with the received job data and storing the result of the determination of job availability and the received job data; and controlling an execution of the received job data based on the result of the determination of job availability, in response to receiving an execution instruction of the received job data.
Claims17
An image forming apparatus comprising:
- an operation unit;
- and
- one or more controllers having one or more processors and one or more memories, the one or more controllers configured to:
- register strings;
- receive job data;
- determine a job availability of the received job data based on a comparison of text information from the received job data with the registered strings before reception of an execution instruction of the received job data;
- store the received job data associated with the result of the determination of job availability of the received job data;
- and
- control an execution of the received job data based on the result of the determination of job availability in response to receiving the execution instruction of the received job data via the operation unit.
A control method for an image forming apparatus having an operation unit and a storing unit, the control method comprising:
- registering strings;
- receiving job data;
- determining a job availability of the received job data based on a comparison of text information from the received job data with the registered strings before reception of an execution instruction of the received job data;
- storing, in the storing unit, the received job data associated with the result of the determination of job availability of the received job data;
- and
- controlling an execution of the received job data based on the result of the determination of job data availability in response to receiving the execution instruction of the received job data via the operation unit.
