A print head includes: a mounting board; a light source portion that includes a plurality of light emitting elements provided on one surface of the mounting board; a drive member that is provided on other surface of the mounting board so as to generate a lighting signal and drive the light source portion; and a first temperature detector that is provided on the mounting board, and at least one second temperature detector that is provided at a farther position on the mounting board from the drive member than the first temperature detector; and the drive member includes: a light emitting unit that generates the lighting signal based on a temperature detected by the first temperature detector and a temperature detected by the second temperature detector; and an optical unit that forms an image of light emitted from the light emitting unit.

An image forming apparatus includes a replenishment empty history recording portion, a post-empty attachment detecting portion, and an image creation restricting portion. The replenishment empty history recording portion records replenishment empty history information to a storage device in correspondence with one of the plurality of developer containers in which a replenishment empty state was detected in a first attachment portion. The post-empty attachment detecting portion detects whether or not a second attachment portion is in a post-empty container attached state where the developer container corresponding to the replenishment empty history information recorded in the storage device is attached to the second attachment portion. The image creation restricting portion, upon detection of the replenishment empty state, restricts an operation of an image creating device, and upon detection that the second attachment portion is in the post-empty container attached state, releases a restriction on the operation of the image creating device.

An information processing device includes: an acquisition unit configured to acquire a determination result of a state of a user, who has given a transmission job execution instruction, determined based on biological information of the user; and a job control unit configured to control an execution of the transmission job according to the user state determination result, wherein when it is determined that the user is in an off-normal state, the job control unit executes a confirmation request process to request the user to make a confirmation related to the transmission job.

According to one example of the present invention there is provided a method of printing, with a printer, an image on a substrate, the printer comprising a substrate support. The method comprises obtaining an image to be printed, determining an offset position of a substrate positioned on the substrate support relative to a predetermined reference printing position, and controlling the printer to print the image to be printed at the determined offset position.

It is an object of the present invention to improve visibility for observation with naked eyes or for camera shooting without spoiling the appearance during marking inside a. transparent medium using a laser. By irradiating an inside of a transparent medium with a laser, the present invention forms a micro-denatured region in each of a first layer and a second layer inside the medium. The micro-denatured regions in the respective layers are arranged out of alignment with each other on a two-dimensional plane (refer to FIG. 1).

A receipt printing apparatus comprises a printer including a processor and a printing unit that is capable of printing on a printing medium. A registration device is connected to the printer. The printer stores a control program that when implemented by the processor causes the printer to acquire transaction details from the registration device, to receive a selection of a first output receipt type and a second output receipt type, and to output the transaction details in the selected one of the first output receipt type and the second output receipt type.

An image forming apparatus performs a first preparation operation in a full color mode when power is supplied. The apparatus performs, when an image formation request is inputted after the first preparation operation completes, a second preparation operation in a designated color mode in accordance with the image formation request. When an image formation request is inputted during the first preparation operation, the apparatus skips the second preparation operation and performs image formation after the first preparation operation completes.

An optical print head comprises a first light emitting element row, a second light emitting element row, a lens array, a first drive circuit and a second drive circuit. The first light emitting element row includes the arrangement of first light emitting elements. The second light emitting element row includes second light emitting elements arranged in parallel with the first light emitting element row. The lens array concentrates light emitted by the first light emitting elements and the second light emitting elements. The first drive circuit drives each first light emitting element with an identical first current value. The second drive circuit drives each second light emitting element with an identical second current value different from the first current value.

A print controller includes a communication section configured to communicate with a printer, a communication controlling section configured to request transmission of a transmission command for acquiring response data to the printer, and a printing data processing section configured to process printing data on a host-based system and transmit the processed printing data to the printer via the communication section. During communication on the host-based system, the printing data processing section transmits the transmission command to the printer via the communication section and acquires the response data returned from the printer in response to the transmission command. The communication controlling section processes the acquired response data as response data corresponding to the transmission command.
