A processing apparatus capable of preventing a function corresponding to a contract from becoming unavailable due to an external factor. A communication unit has communication with an information management server to confirm a contract. A determination unit determines whether a failure factor of contract confirmation is an external factor. A controller stops providing a function corresponding to the contract in a case where the contract confirmation fails and it is determined that the failure factor of the contract confirmation is not the external factor, and provides the function corresponding to the contract in a case where the contract confirmation succeeds or a case where the confirmation of the contract fails and it is determined that the failure factor of the contract confirmation is the external factor.

Processing apparatus provisioned with multiple functions pursuant to confirmation of a contract and control method therefor

An application operating on a first apparatus transmits a change request to a second apparatus in response to a user's operation on the application, and a browser operating on the first apparatus periodically transmits an update request for a screen displayed in the browser to the second apparatus. If an update request received from the first apparatus that is the same as a transmission source of the change request is an update request received for the first time since the change request is received from the first apparatus, the second apparatus transmits a screen corresponding to the change request to the first apparatus as a response to the update request.

System and printing apparatus for performing transmitting processing for an application and browser, and methods for the system and the printing apparatus

An image forming apparatus conveys a printing medium at a first conveyance speed when a number of copies to be printed is smaller than a predetermined number, and conveys the printing medium at a larger second conveyance speed when the number of copies to be printed is larger than the predetermined number. When the numbers of copies to be printed of the first and second print jobs are smaller than the predetermined number, and printing mediums to be used for a first print job and a second print job are conveyed at the first conveyance speed, or when the numbers of copies to be printed of the first and second print jobs are larger than the predetermined number, and the printing mediums to be used for the first and second print job are conveyed at the second conveyance speed, continuous printing of the first and second print jobs is possible.

Image forming apparatus having controlled conveyance speed, image forming method, and storage medium

An image forming apparatus performs printing based on a print job and determines whether printing for a first print job and a second print job having been received after the first print job can be made continuously based on a progress of printing for the first print job. In a case where it is determined that the printing for the first print job and the second print job can be made continuously, print media to be used for printing for the second print job is fed to a conveyance path before completing outputting printouts for the first print job.

Image forming apparatus and image forming method with continuous printing

A communication apparatus receives a use request to use a function of the communication apparatus from an external device via a communication unit. When the use request is received, the communication apparatus acquires a first identifier for identifying the external device as a request source which requests the use of the function. Based on the acquired first identifier and a second identifier for identifying an external device which requests power supply by a power transmission unit, the communication apparatus determines whether to cause the power transmission unit to transmit power to the external device. If it is determined to transmit power, the communication apparatus transmits, via the power transmission unit, power to the external device which requests power supply.

Communication apparatus, control method therefor, and computer-readable storage medium

This invention suppresses power consumption of a mobile communication terminal apparatus in data exchange in wireless communications. For this purpose, when wireless communications are established between a mobile communication terminal apparatus () and MFP (), the mobile terminal () sends a processing request to the MFP (). Upon reception of this request, the MFP () re-establishes communications with the mobile terminal () so as to set a communication mode in a passive mode, and to share roles to have the MFP as an initiator, and the mobile terminal as a target.

Apparatus and method

A control method using a print head for printing a plurality of images on a continuous sheet has the steps of obtaining information in regard to a position and a level of a unique portion unsuitable for image printing that exists on the continuous sheet and of causing a maintenance operation of the print head by using a region where the unique portion exists on the continuous sheet based upon obtained information.

Control method, printing sheet used therefor, and printing apparatus

A control apparatus, comprising a reception unit configured to receive image data, a setting unit configured to set an operation mode, an image processing unit configured to generate print data based on the image data, a print control unit configured to cause a printing unit to perform printing on a printing medium based on the print data, a determination unit configured to determine whether reception of all the image data is complete before the printing unit completes predetermined printing, and a change unit configured to change the set operation mode to another operation mode in a case where the set operation mode is an operation mode in which printing based on the print data starts if the image processing unit generates the print data.

Control apparatus, control method, and non-transitory computer-readable storage medium

In a push scan of a web services on devices (WSD) scan service, an information terminal apparatus performs a registration request to receive a service from a reading apparatus. A name of the information terminal apparatus is included in the registration request command, and a user can select the name of the information terminal apparatus as a destination of scan data when executing the push scan from the reading apparatus. However, at this point of time, a user name which is logging on the information terminal apparatus cannot be recognized. For this reason, a requisition command of an operation start request is issued to the information terminal apparatus on a network before the information terminal apparatus as a destination of image data is selected through a display unit of the reading apparatus. Therefore, a log-on user name extracted from a command including the log-on user name transmitted from the information terminal apparatus can be displayed on the display unit.

Method for acquiring user identification information of destination apparatus under WSD protocol before sending read image data

Images are sequentially printed on a first surface of a sheet, and identification information for identifying an image is formed each time an image is printed. When printing is interrupted by the error and before resuming printing, the identification information formed on the first surface of the sheet fed from the reverse unit again is read by the reader, and an image to be printed on the second surface when resuming printing is specified based on the read identification information.

Printing apparatus and method for duplex printing

In a system in which an information processing apparatus and a peripheral are connected to each other. Initially, the information processing apparatus transmits, to the peripheral, a request to use a service provided by the peripheral. The peripheral determines whether to grant use permission to the received request, and notifies the information processing apparatus which has transmitted the request of the determination result. The peripheral stores information associated with the information processing apparatus to which use permission is granted in response to the request. The information processing apparatus then receives, from the peripheral, a response to the request.
