In a case of a first function of carrying out a cooperative processing in accordance with an instruction from a user of a multifunction peripheral (10), the user is set as an execution user. In a case of a second function of carrying out a cooperative processing in accordance with an instruction from an application, a user instructed by the application is set as an execution user. Further, in a case where an execution user of a cooperative processing carried out using the first function and an execution user of a cooperative processing carried out using the second function are identical, use history information of the execution user is managed as use history information of a single user. This makes it possible to appropriately manage use history information of a cooperative processing.

If the printing protocol associated with a received print job is not an internet printing protocol, the number of times of printing is counted for each type of printing protocol. If the printing protocol associated with a received print job is an internet printing protocol, the number of times of printing is counted while distinguishing a transmission source application by identifying a transmission source application.

A method for importing information regarding a user into an information processing apparatus, the information processing apparatus comprising storage that stores personal setting information corresponding to a user that uses the information processing apparatus, and last login time and date of a user that uses the information processing apparatus, includes receiving an import instruction of data including at least one piece of user information, and personal setting information associated with the user information, and identifying, when executing import processing based on the data in response to the import instruction, a user whose personal setting information is to be deleted, based on last login time and date stored in the storage, and deleting personal setting information stored in the storage in association with the identified user so that the personal setting information does not reach a registration upper limit after import.

An image log management apparatus manages image data indicating an execution result of an image processing job on an image processing apparatus, as an image log, and includes: a hardware processor that: performs detection of whether a predetermined reference image is included in the image data related to the image processing job; and restricts storage of an entire image or a partial image as an image log, out of images represented by the image data, in a case where the reference image is detected.

An example device capable of predicting print substance end-of-life (EOL) comprises a container to hold a print substance, the container comprising a refill port through which print substance is to be introduced into the container. The example device also comprises a processor to receive signals indicative of an amount of print substance introduced via the refill port. The processor is also to predict a print substance end-of-life (EOL) based on the amount of print substance introduced.

Methods and apparatus for predicting colorant usage by printing devices are provided. A prediction server can receive a request to predict colorant usage for a first printing device. The prediction server can determine first plurality of functions to predict colorant usage for the first printing device. The first plurality of functions can include at least one linear function and at least one non-linear function. The first plurality of functions can be based on colorant-usage rates indicating historical rates of change in colorant used by the first printing device. The prediction server can determine a prediction of colorant usage for the first printing device using the first plurality of functions. The prediction server can provide an output involving the prediction of colorant usage for the first printing device, where the prediction of colorant usage can include a confidence interval related to the prediction.

An image processing apparatus includes at least one of an image forming device configured to form an image on a sheet or an image reader configured to read an image on the sheet, and a storage configured to store information. The apparatus also includes a display configured to display a screen, and a controller. The controller is configured to install an application program relating to the image forming device or the image reader, determine whether to display an execution instruction image for inputting an execution instruction of the installed application program on an individual home screen which is a home screen for individual use by each user, and display the individual home screen containing the execution instruction image determined to be displayed on the display.

A communication apparatus comprises: a sending unit that sends data to a designated destination; a receiving unit that receives a response to the send by the sending unit; a recording unit that records information relating to a send when the send is performed by the sending unit, and associates and records, when a response to the send is further received by the receiving unit, information of a send-source of the response; and a control unit that causes the sending unit to resend data based on information recorded in the recording unit, wherein the control unit causes the sending unit to resend data to a destination indicated by information, among the recorded information, for which a predetermined time has elapsed since the recording and for which a response has not been received by the receiving unit.

If the printing protocol associated with a received print job is not an internet printing protocol, the number of times of printing is counted for each type of printing protocol. If the printing protocol associated with a received print job is an internet printing protocol, the number of times of printing is counted while distinguishing a transmission source application by identifying a transmission source application.

Registration in an address book from a transmission history which may lead to erroneous transmission is prohibited, and other address book registration and the like are enabled, so that erroneous transmission can be prevented without impairing convenience.
