A data processing apparatus is configured to receive a selection of a first function and search for one or more devices which has the capability to perform that first function. The apparatus may then receive a selection of the one or more devices for performing that first function and, in conjunction, determine whether the selected device has the capability to execute a second function. The device identification data may be stored. Subsequently, if the selected device is determined to be capable of executing the second function, which is different from the first function selected, and the second function is further selected, the previously selected device may be displayed as having the capability to execute the selected second function. Otherwise, the apparatus does not display the previously selected device as being able to execute the selected second function.

An image forming apparatus including applications and system side software for providing system side services to the applications is provided, in which the image forming apparatus includes: an authentication module for displaying an authentication screen on an operation panel of the image forming apparatus, wherein the authentication module allows the image forming apparatus to display a screen for using the image forming apparatus instead of the authentication screen if authentication data input from the authentication screen satisfies an authentication condition, and wherein the authentication module is provided in the image forming apparatus separately from the system side software.

A function executing device is configured to send a wireless identifier to a communication device via a first type of wireless communication interface for setting up a wireless connection. The function executing device is configured to determine whether the function executing device is in an error state and, if not, to establish the wireless connection via a second type of wireless communication interface. The function executing device operates in a parent state in the wireless connection. Additionally, print data may be received from the communication device. However, if the function executing device is in an error state the wireless connection is not established via the second type of wireless communication interface.

On a touch-panel display of an image forming apparatus, which is divided to five areas, that is, a system area, a function selection area, a preview area, an action panel area and a task trigger area, pieces of information are displayed. Even if an operational mode is switched, the same or similar information is always displayed in the area arranged at the same position. In the task trigger area, software buttons operated by the user for actually operating the image forming apparatus are displayed.

An image processing apparatus which reads an image of a document and prints the read image on a sheet includes a detecting unit, an obtaining unit, and a controller. The detecting unit detects a size of the document. The obtaining unit obtains a size of the sheet. The controller performs control such that, in a case where the size of the sheet obtained by the obtaining unit is not a predetermined size, an image in a reading region based on the size of the document detected by the detecting unit is read, and in a case where the size of the sheet obtained by the obtaining unit is the predetermined size, an image in a reading region based on the size of the sheet is read.

There is provided a controller configured to execute: obtaining of color values of picture elements, respectively, of P pieces of target picture element columns; identifying of a blank picture element, indicating a white color as a brightest color; and identifying a candidate picture element line as a blank line which is a picture element line indicating the white color as the brightest color, the candidate picture element line being constructed of T pieces of picture elements arranged side by side in a second direction and including the P pieces of target picture elements located at a same position in the first direction, in a case that the candidate picture element line satisfies a first blank line condition, wherein the P is a integer in a range of not less than 2 to less than the T.

An image forming apparatus includes an operation device that is connected to the image forming apparatus and receives an operation to the image forming apparatus; a processing unit that performs a predetermined processing by a first application in the image forming apparatus or the operation device; an error detecting unit that detects the error in the processing by the first application; a control unit that starts up a second application to resolve the error upon the error is detected; a transmission unit that transmits error data formed based on the contents of the error from the first application to the second application; and a display unit that displays the operation screen of the second application based on the error data.

A job processing apparatus that is capable of positively stopping a transmission job desired by a user. A transmission job is input according to a user's operation. Uncompleted transmission jobs out of input transmission jobs are managed by a job management table. A first stop instruction for stopping a transmission job is received according to a user's operation. In a case where the first stop instruction is received during display of a configuration screen for making settings of a transmission job, a transmission job input last out of the transmission jobs managed by the job management table is searched for, and the searched-for transmission job is stopped.

An image processing apparatus which reads an image of a document and prints the read image on a sheet includes a detecting unit, an obtaining unit, and a controller. The detecting unit detects a size of the document. The obtaining unit obtains a size of the sheet. The controller performs control such that, in a case where the size of the sheet obtained by the obtaining unit is not a predetermined size, an image in a reading region based on the size of the document detected by the detecting unit is read, and in a case where the size of the sheet obtained by the obtaining unit is the predetermined size, an image in a reading region based on the size of the sheet is read.

An image forming apparatus includes a speech input device, a display device, an image forming device, and a control device. The display device displays an image expressed in a preset language for display. The control device functions as a controller that operates in either one of a normal operating mode and an emergency operating mode and recognizes, based on a speech input to the speech input device, a language of the input speech. During operation in the normal operating mode, the controller recognizes a language of the speech input to the speech input device and sets the recognized language as the language for display. During operation in the emergency operating mode, the controller recognizes a language of the speech input to the speech input device and allows the image forming device to form an image representing evacuation information expressed in the recognized language.
