BACKGROUND OF THE INVENTION
The present invention relates to an image forming system including a plurality of image forming apparatuses. Interrupted by any of the plurality of image forming apparatuses The suspended job Any of the plurality of image forming apparatuses The present invention relates to a suspended job resuming method for resuming and an image forming system.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there has been developed and provided an image forming apparatus capable of resuming a job being executed for at least a limited function such as interrupt copying and then restarting the job.
[0003]
In addition, an image forming apparatus has been proposed in which print information related to job interruption and resumption is stored on a movable medium, so that a job interrupted by one apparatus can be resumed by another apparatus. In this system consisting of image forming devices, print information related to job suspension and resumption is transferred via a removable storage medium, so that the user's movement to carry a physical storage medium just corresponds to the movement of an interrupted job It provides a user-friendly and reliable operation model. According to this clear operation model, even if a plurality of users have interrupted jobs at a certain point in time, the job of the user who operates the apparatus for resumption can be reliably resumed.
[0004]
On the other hand, an image forming apparatus installed in a store such as an office or a convenience store and used by many users is designed to be shared by multiple users, but unlike computers such as engineering workstations, In many cases, a user management mechanism for identifying and controlling each user to whom a job executed by an image forming apparatus belongs is not provided at all, and even if it is provided, it has not been fully utilized.
[0005]
For example, a copying machine used in a convenience store or the like is controlled so that the apparatus can be used by depositing money such as coins into a fee collection apparatus connected to the apparatus. However, in such a copying machine, the user related to the job to be input has not been specified.
[0006]
For example, in a copier used in an office or the like, the department is identified from a mechanism for inputting a department code and a personal identification number for identifying a department such as a department or section, or a card such as a magnetic card or an IC card. And a mechanism for reading information for the user, and the apparatus is controlled to be usable after the department to which the user belongs is authenticated. However, in such a copier, even if the department to which the user related to the submitted job is identified, the identified department information is statistical processing for counting the amount of use of the device for each department, accounting for usage charges, Alternatively, it is only used for use restriction processing so as not to exceed a predetermined use restriction preset for each department. Similarly, in copiers, printers, faxes, etc. shared by multiple customers at business hotels, etc., the specified room information is charged for the use of the device even if the user's room number related to the job is specified. It was only used to account for the billing included in the room at checkout.
[0007]
Further, for example, printers used in offices and the like are generally used in combination with computers such as engineering workstations and personal computers. Therefore, when a print job is input from the computer to the printer, the computer There has been proposed a printer that receives user identification information in the user management mechanism as additional information of a job. In such a printer, the received user information may be printed on a banner page for separating print output sheet bundles of a plurality of jobs, and may be used to easily collect the print results of the jobs that the user has input. It was.
[0008]
Further, in the secure print function for controlling to discharge the print output paper only when the user inputs user identification information and a password later to the printer without discharging the print output paper at the time of job input, User information received with a job may be used.
[0009]
Alternatively, in a print server that can schedule a plurality of print jobs by spooling a plurality of print jobs, the print job registered in the print queue (queue) is permitted to be interrupted, resumed, canceled, and changed in priority. In some cases, the user information received together with the job by the print server may be used in order to give the operation authority only to the job submitted by the user and to prohibit the operation on the job submitted by another user.
[0010]
[Problems to be solved by the invention]
However, the conventional image forming apparatus and the image forming system constituted by a plurality of image forming apparatuses have the following problems.
[0012]
The conventional image forming apparatus designed on the premise of sharing by a plurality of users does not include a user management mechanism for identifying and controlling each user to which the job to be executed belongs, or even if provided. Because it was not fully utilized, when resuming a job that was interrupted, the user had to select a job related to him from among the jobs that others had interrupted, which tended to be cumbersome. . That is, there is a problem that the other person's hold job is bothered.
[0013]
In addition, there was a concern that a job held on its own could be inappropriately manipulated by others.
[0014]
Also, since it is not necessary for the user to forget about the existence of a pending job, the system wants the system to automatically call attention. On the contrary, it is complicated.
[0015]
The present invention has been made to solve the above-described problems, and can easily select and resume a desired job from among a large number of held jobs, and can be easily interrupted with appropriate attention to the existence of a held job. Understand job hold status, and each user under appropriate access control At the desired image forming device Can handle suspended jobs Do For the purpose.
