Information on printer maintenance or an updating of software is notified without giving uncomfortable feeling to a user by an unintentional change of screen displays. The invention comprises an application activating unit which issues an application binding command in response to a print instruction of a data generated by an application executed by a mobile, an additional information acquiring unit which acquires an additional information according to a predetermined information acquiring command included in the application binding command when a print result information is acquired from the printer, and an information providing unit which provides the mobile with the additional information in addition to the print result information. A user is notified of necessary information on printer maintenance or an updating of software in addition to the print result information upon completion of printing intentionally instructed by the user.

In a case where a plurality of users share the use of one mobile terminal, an image forming apparatus has performed authentication printing also on image data to which the previous owner of the mobile terminal has sent a printing instruction. According to the present embodiment, an image forming apparatus includes a data reception unit configured to receive data having a device ID of a mobile terminal and user information for identifying a user of the mobile terminal, and includes an authentication information reception unit configured to receive authentication information including the device ID and the user information from the mobile terminal. The image forming apparatus also includes a print control unit configured to control, in response to the reception of the authentication information, a printer to print the data received by the data reception unit.

A composite apparatus includes a recording device, a reading device that is disposed on the recording device and is able to read an image, a recording portion that is disposed within the recording device and is able to perform printing by ejecting ink on a paper sheet P, and a liquid accommodating portion that is disposed on a side portion of the recording device and which accommodates the ink to be supplied to the recording portion, in which the reading device is disposed such that a part of the reading device protrudes from the recording device to above the liquid accommodating portion.

Aspects of the disclosure provide an electronic device comprising a controller. The controller to determine a volume of print fluid in a first tank of the electronic device, monitor current printing conditions of the electronic device disposing print fluid on a substrate, determine, based on the volume of print fluid and the current printing conditions, whether an adverse printing condition exists, responsive to the volume of print fluid being less than a threshold and the adverse printing condition not existing, control a pump to refill the first tank from a second tank at a flow rate determined at least partially according to the determined volume, and responsive to the volume of print fluid being less than the threshold and the adverse printing condition existing, control the pump to refill the first tank from the second tank at a default flow rate determined independent of the determined volume.

A head attachment/detachment jig that is used for attachment/detachment of a head which ejects ink droplets and is fixed on a base member by a fastener member when replacing the head, the head attachment/detachment jig, includes a frame member that is attachable to and detachable from the head; and a tip tool that has a tip part and a top part, and is held to be turnable and movable forward and backward with respect to the frame member, wherein the tip part of the tip tool has a shape that is capable of turning the fastener member, and the top part of the tool has a shape that is formed to be capable of turning the tip tool by a different tool from the tip tool.

The invention facilitates a setting state updating operation of the printer. An updating system of a setting state of a printer comprises an application activating unit which issues an application binding command upon detection of a predetermined operation when an application is executed by a mobile. The application binding command designates a printing application and a predetermined setting state updating command. The updating system further comprises a setting state updating unit which executes an updating of the setting state of the printer in the printing application activated by the application activating unit according to the predetermined setting state updating command included in the application binding command. A predetermined operation in the application triggers activation of the printing application for an automatic updating of the printer setting state.
