An image processing apparatus includes a storage unit in which a usage quantity of each of the functions is stored, and a processor configured to control activation of the application, based on the usage quantity of the function employed by the application.

An example method of setting ink limits for a printing system is described. The method involves printing a first set of color ramps. Each color ramp has test areas which are printed based different Neugebauer Primary Area Coverage (NPac) vectors. A test area for each color ramp is indicated that meets an image quality metric and Neugebauer Primary ink use limits are set based on these test areas. A second set of color ramps, for combinations of the set of available Neugebauer Primaries, is then printed, The test areas for each ramp are defined by monotonically-varying vector element values for one Neugebauer Primary in a combination and the second set of ramps are defined by monotonically-varying vector element values across said ramps for another Neugebauer Primary in the combination. Test areas are then indicated again for the second set of color ramps to set ink use limits for the printing system.

An image forming system includes an image forming apparatus, a management terminal device, and a mobile terminal device. The mobile terminal device downloads and installs an application program, presents identification information to the management terminal device, and accepts a temporal ID. The management terminal device, upon accepting the identification information from the mobile terminal device, generates the temporal ID, presents the temporal ID to the mobile terminal device, and transmits the temporal ID to a user authentication device to register the temporal ID as a user ID of the guest user. When payment of a usage fee for the image forming apparatus by the guest user is completed, the management terminal device deletes registration of the temporal ID. The image forming apparatus performs user authentication when the guest user logs in to the image forming apparatus, and issues an invoice when the guest user logs out.

A system and a method for processing documents using mobile payment to instantly activate privilege are provided with a mobile device, a cloud server, a proxy server and a document-processing device connected to a network. Users can hold the mobile device to approach the document-processing device to perform corresponding operation in generation of a setting of parameters. The cloud server acquires the setting of parameters through the network and transmits the setting of parameters to the proxy server in exchange for dedicated pictogram authentication information. The document-processing device provides pictogram information according to the pictogram authentication information. The mobile device performs and completes a payment procedure according to the pictogram information. The cloud server then instantly transmits an execution command to drive the document-processing device so as to enhance operational convenience and efficiency.

An image processing apparatus includes a storage unit in which a usage quantity of each of the functions is stored, and a processor configured to control activation of the application, based on the usage quantity of the function employed by the application.

A server includes a controller The controller acquires device-usage information, which indicates a status of use of a subscribed device which is a device subscribing to a service, from the subscribed device, generates service-usage information indicating a status of use of the service, based on the acquired usage information, acquires an exchange request for changing the subscribed device from a first device currently subscribing to the service to a second device different from the first device, and changes the subscribed device from the first device to the second device, in response to the acquired exchange request.

A recording system includes: an information processing device including an input interface and a display unit; and a recording device including a recording unit that executes a recording operation on a recording medium, the recording device being configured to control the recording unit to execute the recording operation within a range of a recording permission amount for permitting the recording operation by the recording unit, wherein the recording system is configured to execute a tutorial process such that, in the tutorial process, a tutorial operation screen for notifying a guidance to a user about a charge operation is displayed on the display unit, the charge operation being an operation on the input interface for purchasing the recording permission amount.

An output system includes an output section, a fee calculation section, and a payment code notification section. The output section outputs an image and/or a document. The fee calculation section calculates a fee necessary for outputting the image and/or the document in accordance with a specific standard. The payment code notification section notifies a payment code issued by an online payment service for the fee calculated by the fee calculation section. The output section outputs the image and/or the document when the fee has been paid via the online payment service using the payment code notified by the payment code notification section.
