The image forming apparatus according to any one of claims 1 to 3, wherein if the matching of the matching information is not performed even after a predetermined time has elapsed since the request for the matching information , the processor postpones printing the output page and processes subsequent output pages.
The image forming apparatus according to any one of claims 1 to 4, wherein the processor detects a specific page by detecting predetermined information in the print data and obtains user information for authenticating the user as the matching information.
The image forming apparatus according to claim 5 , wherein the predetermined information is predetermined characters or marks placed at predetermined positions.
The processor comprises, By detecting predetermined information within the print data to be printed, a specific predetermined page is detected. Obtain user information as matching information to authenticate the user, An information processing device that, when it detects the aforementioned specific page, sends to the image forming apparatus a print information to be printed , including information specifying the specific page and the matching information, in order to cause the image forming apparatus to embed the matching information by rewriting the information of the leading portion outside the print area of the image data of the output page containing the aforementioned specific page.
The information processing device according to claim 7 , wherein the predetermined information is predetermined characters or marks placed at predetermined positions.
An image forming apparatus according to any one of claims 1 to 6 , An information processing device that transmits print data to be printed and the print information to the image forming apparatus to request printing, An image forming system including [specific components].
An image forming apparatus according to any one of claims 1 to 4 , The information processing apparatus according to claim 7 or claim 8 , An image forming system including [specific components].
On the computer, The system acquires print information, which is setting information including a predetermined specific page and predetermined matching information, and print data for the print target to be drawn . The print data to be printed is converted into image data in a printable format for each output page. By rewriting the information of the leading portion outside the print area of the image data of the converted output page, which includes the aforementioned specific page, the matching information is embedded. By referring to the information at the beginning of the aforementioned image data, it is determined whether or not the matching information is embedded. If it is determined that the aforementioned matching information is not embedded, print the output page. If it is determined that the aforementioned matching information is embedded, the system requests and obtains the aforementioned matching information from the user. An image forming program for causing the program to print the output page when the embedded matching information matches the acquired matching information.
On the computer, By detecting predetermined information within the print data to be printed, a specific predetermined page is detected. Obtain user information as matching information to authenticate the user, An information processing program for sending information specifying the specific page and the matching information to the image forming apparatus, along with the print information to be printed, to the image forming apparatus in order to embed the matching information by rewriting the information of the leading portion outside the print area of the image data of the output page containing the specific page when the image forming apparatus detects the specific page and requests printing from the image forming apparatus.

Description

This invention relates to an image forming apparatus, an information processing apparatus, an image forming system, an image forming program, and an information processing program. Patent Document 1 proposes a control device installed in a location that ensures output from a printer, or one that is built into a printer. This control device includes an authentication function that authenticates the execution of a print job transmitted from a host device via a communication network to be output from the printer by providing authentication information at close range to the control device; a power control function that starts supplying power to the printer upon authentication by the authentication function; and a virtual host function that provides the print job to the printer upon authentication by the authentication function. Patent Document 2 proposes a printing system having a printing device capable of receiving multiple print jobs. In the event of a printing interruption, the system stores the data to be printed in an encrypted state in a storage means when the printing process of a print job is interrupted by the interruption. The system then allows the printing device to resume the printing process of the print job after decryption of the encrypted data stored in the storage means, once the interruption has been resolved and the authentication data required for resuming printing has been input. Patent Document 3 describes a printing system capable of secure printing, in which a secure print is specified on a page-by-page basis for a print job generated in a host computer that generates the print job, and furthermore, the printing device performs secure printing on a page-by-page basis. For print jobs where "CuredPrint" is specified, it is proposed that all pages except those specified be printed without user authentication, and only the specified pages be printed after authentication.
