An apparatus includes: a generation unit that generates a PWM wave based on a sound signal; and a processing unit that converts the PWM wave to a square wave. The processing unit includes: a first counter that determines a pulse width of the PWM wave; a comparison unit that compares a first difference value, obtained by subtracting the pulse width in a second cycle being a cycle immediately preceding a first cycle from the pulse width in the first cycle, and a second difference value obtained by subtracting the pulse width in a cycle immediately preceding the second cycle from the pulse width in the second cycle; and an output unit that outputs the square wave while switching a state thereof in a case where a sign of the first difference value changes from that of the second difference value.

A digital camera with a printer is a digital camera with a printer and includes a communication unit that communicates with a digital camera with a printer that is another apparatus, and an image composition unit that generates a composite image in which a first image captured by the digital camera with a printer that is an owned apparatus and a second image captured by the other apparatus are composited, in which the communication unit transmits the composite image to the other apparatus. A user of the other apparatus can also obtain the composite image. Accordingly, the composite image can be enjoyed by capturing images using a plurality of cameras.

An example user terminal apparatus includes a display, a communication apparatus to communicate with an external apparatus, and a processor to, based on information on a possible first toner refill quantity of a plurality of grouped image forming apparatuses provided from the external apparatus through the communication apparatus and a toner quantity of one toner refill apparatus, control the display to display a guide message including information on the time point of toner refill, each of the image forming apparatuses which is a subject of toner refill within the group, and a possible second toner refill quantity of each of the image forming apparatuses at the time point of toner refill.

An information processing apparatus being communicable with a web server configured to provide a web page being capable of accepting instructions to control a printing apparatus, includes: a first obtaining unit configured to obtain a certificate of the web server; a verifying unit configured to verify the certificate; and a communicating unit configured to establish secure communication with the web server in a case where the verifying unit succeeds in verification and to establish unsecure communication with the web server in a case where the verifying unit fails in the verification.

A terminal device may receive notification information from a notification server and selectively display one screen among a plurality of screens on a display. The terminal device may, in a case where a predetermined condition is satisfied and a first screen among the plurality of screens is displayed, display the notification information on the first screen. The terminal device may, in a case where the predetermined condition is satisfied and a second screen among the plurality of screens is displayed, not display the notification information on the second screen, and in a case where the predetermined condition is not satisfied, not display the notification information.

A system for providing print device dynamic status indicator feedback includes a print device, and a status indicator feedback unit. The print device includes a print engine and one or more status monitors. The status indicator feedback unit includes a display device, a light emitting module, a processor in communication with the light emitting module, and a computer-readable medium containing programming instructions. The system may receive information corresponding to one or more current machine states of the print device from the one or more status monitors of the print device, determine a priority level associated with each of the one or more current machine states, identify a machine state associated with a highest priority level, identify a dynamic feedback pattern associated with the identified machine state. The dynamic feedback pattern includes a visual pattern. The system may and instruct the light emitting module to emit the visual pattern.

An image forming apparatus includes: a display portion; an error sensor that detects an operating error; a recovery sensor that detects the recovery from an operating error; and a display processor that makes the display portion display a notice of an operating error when the error sensor detects the operating error and that makes the display portion display an operation guide for preventing the reoccurrence of the same operating error when the recovery sensor detects the recovery from the operating error.

A system for providing multifunction device (MFD) status information to a user includes an MFD and a light projection unit. The MFD may include a print engine and one or more status monitors. The light projection unit may include a light projecting module, and a processor for receiving information corresponding to a current machine state of the MFD from the status monitors of the MFD. The processor may identify an area of the MFD that corresponds to the current machine state, and identify a projected light pattern associated with the current machine state. The projected light pattern includes a visual pattern created using projected light. The processor may instruct the light projecting module to project the identified projected light pattern proximate to the identified area of the MFD.

A display device includes the following elements. An obtaining unit obtains a processing description and a processing state of each processing operation. A specifying unit specifies a processing state. A first display controller performs control so that a processing description of a processing operation belonging to the specified processing state is displayed in a first region. A second display controller performs control for each processing state so that an image reflecting the number of processing operations belonging to the corresponding processing state is displayed in a second region, and so that, if the number of processing operations belonging to a processing state that is not specified is changed, an image reflecting the changed number is redisplayed in a first mode and, if the number of processing operations belonging to a specified processing state is changed, an image reflecting the changed number is redisplayed in a second mode.

A prompting method includes determining to use a custom prompting manner to prompt a status of an image forming apparatus, in response to detecting that the status of the image forming apparatus satisfies a prompting condition, generating a custom prompting message corresponding to the status of the image forming apparatus, and presenting the custom prompting message to a user.
