First and second printing apparatus are in an intranet and a bibliography server connected to the Internet. The bibliography server being configured to manage bibliographic information of print data. The first printing apparatus acquire a list of print data from the bibliography server, when an instruction to print out print data included in the list is received from a user with an operating unit of the first printing apparatus, sends identification information for identifying the print data to the second printing apparatus and when a print request is received, prints out print data included in the received print request. The second printing apparatus sends bibliographic information of print data received from an external apparatus to the bibliography server; and sends a print request containing the print data identified by the identification information to the first printing apparatus.

A varied least recently used (VLRU) caching technique is used to enable print data to be available at a cache of a client for printing, even after an agent performs a deletion of a hash value for the print data at a cache of the agent. The deletion of the print data (cached at the cache of the client) is postponed at the client device via the use of a waiting list, so that the cached print data can be printed at a physical printer of the client, in response to receiving a delayed print job from the agent that specifies the hash value as a result of a deduplication process performed by the agent.

A printer includes a control unit and a printing unit. The control unit determines whether a portion of the print image referred to as a target region is blank. The printing unit cancels printing of the print image when the control unit determines that the target region is blank.

A printing system includes a printer configured to perform an issuance process of issuing a cancel notification in response to detecting a cancel trigger, and a non-transitory computer-readable medium storing computer-readable instructions that, when executed by a processor connected with a communication interface, cause the processor to cancel a generating process of generating print data and a print instruction process of transmitting print instruction information to the printer via the communication interface, in response to acquiring the cancel notification issued by the printer, during the generating process.

There are provided an information processing apparatus and a control method which realize job holding processing while reducing time taken to complete transmission of a job. The control method includes not notifying a spooler of deletion of the job from a job queue after the spooler specifies that transmission of all of pieces of data corresponding to the job is completed and in a case where processing of the job is not completed by a communication apparatus.

The system according to the present disclosure includes a cloud print service (CPS) connected to a client terminal via a network, and a CPS connected to an image forming apparatus through a network. The CPS receives a job executed by the image forming apparatus from the client terminal, and transmits the job to the CPS. The CPS receives a job transmitted from the CPS, issues a job code for the job, and transmits the job code to the CPS. The CPS receives the job code issued by the CPS, and notifies the client terminal of the job code.

An image output device includes a storage and outputs image data stored the storage. The image output device includes a detector, an output controller, and an eraser. The detector detects whether or not specific image information is included in the image data. The output controller allows an output of the image data when the image data does not include the specific image information, and disallows the output of the image data when the image data includes the specific image information. The eraser erases the image data from the storage when the specific image information is included in the image data.

An image formation apparatus to combine a plurality of processes to execute a job related to image formation, the image formation apparatus including: a communicator that sends and receives data to and from an external application via a network, an image data acquirer that acquires image data, an image former that forms an image based on the image data, a storage that stores temporary intermediate data involved in the image formation, a display that displays a message for a user, and a controller that controls the communicator, the image data acquirer, the image former, the storage, and the display; wherein upon performing a process of the plurality of processes, the controller determines whether a next process is present.

A printing system includes a terminal apparatus and a printing apparatus. The terminal apparatus includes: a first inputting section; and a processor configured to: transmit a print request for printing an object image indicated by object data to the printing apparatus; receive first input authentication information inputted by a user; and transmit the first input authentication information to the printing apparatus. The printing apparatus includes: a second inputting section; a printing section; a processor configured to: receive the print request; store the object data and associated authentication information included in the print request while associating with each other in a first memory; receive the first input authentication information; determine whether the first input authentication information matches the associated authentication information; receive input of second input authentication information from the user; and determine whether the second input authentication information matches the associated authentication information.

A printing device includes a printing device communication section configured to receive a print job sent from a host device, a print mechanism configured to perform printing of the received print job, and a printing device control section configured to receive an operation to change a setting of the print job and issue an instruction to send a changed print job in which the setting of the print job has been changed to the host device that is the sender of the print job.
