Abstract

A job status monitoring system includes a job output unit configured to output a job to a job managing unit of an operating system. The job is issued in response to a job issue request. A status of the job output to a printer is monitored by a monitoring unit. The monitoring unit controls the job managing unit by monitoring the status of the job. An application or utility determines the status of the job by obtaining information about the job from the job managing unit and performs display control based on the determined status of the job.

Claims

1. A job status monitoring system capable of communicating with a printer, the job status monitoring system comprising:

a job output unit configured to output a job and a dummy job to a job managing unit of an operating system, the job being issued in response to a job issue request and the dummy job not affecting a print output process,

wherein an application or utility recognizes a status of the dummy job managed by the job managing unit and performs display control based on the recognized status of the dummy job.

2. The job status monitoring system according to claim 1, wherein the printer enables receiving a next job upon an end of a process of a job.

3. A job status monitoring system capable of communicating with a printer, the job status monitoring system comprising:

a job output unit configured to output a job to a job managing unit of an operating system, wherein the job is issued in response to a job issue request and is attached to a dummy job having a size that is larger than a print buffer of the printer,

wherein an application or utility recognizes a status of the dummy job managed by the job managing unit and performs display control based on the recognized status of the dummy job.

4. The job status monitoring system according to claim 3, wherein the system is capable of communicating with the printer in a one-way manner, and wherein the refusal of reception is performed by setting an interface of the printer to busy.

5. A method comprising:

outputting a job and a dummy job to a job managing unit of an operating system, the job being issued in response to a job issue request and the dummy job not affecting a print output process,

wherein an application or utility recognizes a status of the dummy job managed by the job managing unit and performs display control based on the recognized status of the dummy job.

6. The method according to claim 5, wherein the printer enables receiving a next job upon an end of a process of a job.

7. A method comprising:

outputting a job to a job managing unit of an operating system, the job being issued in response to a job issue request and being attached with a dummy job having a size such that a printer refuses to receive the dummy job,

wherein an application or utility recognizes a status of the dummy job managed by the job managing unit and performs display control based on the recognized status of the dummy job.

8. The method according to claim 7,

wherein a job status monitoring system is capable of communicating with the printer in a one-way manner, and

wherein the refusal of reception is performed by setting an interface of the printer to busy.

9. A computer-readable medium having stored thereon instructions which, when executed by a computer, causes the computer to perform a method comprising:

outputting a job to a job managing unit of an operating system, the job being issued in response to a job issue request;

monitoring a status of the job output to a printer; and

controlling the job managing unit based on the monitored status of the job;

outputting a dummy job to the job managing unit of the operating system, the dummy job not affecting a print output process;

recognizing a status of the dummy job managed by the job managing unit; and

performing a display control based on the status of the dummy job,

wherein an application or utility recognizes the status of the job managed by the job managing unit based on information about the job obtained from the job managing unit and performs display control based on the status of the job recognized by the application or utility.

10. A computer-readable medium having stored thereon instructions which, when executed by a computer, causes the computer to perform a method comprising:

outputting a job to a job managing unit of an operating system, the job being issued in response to a job issue request;

monitoring a status of the job output to a printer; and

controlling the job managing unit based on the monitored status of the job,

wherein an application or utility recognizes the status of the job managed by the job managing unit based on information about the job obtained from the job managing unit and performs display control based on the status of the job recognized by the application or utility, and

wherein the job is attached to a dummy job, the dummy job having a size that is larger than a print buffer of the printer.
