In a case where data synchronization between a server and a client is performed by difference synchronization, when the data of the server is restored by backup data, a mismatch occurs between the data held in the client and the data held in the server. If the previous synchronization with the client has been performed before restoring, the client is synchronized with all the data held in the server. If the previous synchronization with the client is after restoring, the server notifies the client of data update contents in the server since the previous update with the client and causes the client to update the held data.

When a registration request of an application button is received, an information processing apparatus generates an image for transition if an activation-completed notification is received. If the activation-completed notification is not received, the information processing apparatus generates the image for transition after the activation-completed notification is received.

A printing apparatus includes a printer unit that prints an image on a sheet, a network controller that instructs the printer unit to execute a preparation operation according to receipt of print data, and a controller that instructs the printer unit to execute the preparation operation according to input of an execution instruction in a case where a reservation function for reserving printing based on the print data received by the network controller until receipt of the execution instruction is received is enabled.

The disclosure includes a fixed retail scanner including a data reader comprising a main board, one or more camera modules, and a multi-port network switch disposed within a housing of the data reader. The multi-port network switch is configured to provide a network backbone for at least some internal devices within the housing of the data reader and for at least some external devices positioned external to the housing of the data reader and operably coupled with the data reader through the multi-port network switch. Related systems may include a remote server operably coupled to the fixed retail scanner through the multi-port network switch such that image data to the remote server may be communicated via the multi-port network switch from at least one of the main board or the at least one camera coupled to the multi-port network switch.

An image forming apparatus includes an obtaining unit that obtains personal setting information about a user who logs into the image forming apparatus from a server apparatus and a display control unit that controls a display unit to display a customized operation screen customized for the user based on the obtained personal setting information. If the personal setting information has been obtained from the server apparatus within a predetermined time, the customized operation screen is displayed. If the personal setting information has been obtained from the server apparatus after the predetermined time elapses, the customized operation screen is not displayed.

A printing apparatus includes a printer unit that prints an image on a sheet, a network controller that instructs the printer unit to execute a preparation operation according to receipt of print data, and a controller that instructs the printer unit to execute the preparation operation according to input of an execution instruction in a case where a reservation function for reserving printing based on the print data received by the network controller until receipt of the execution instruction is received is enabled.

A printing apparatus comprises: a plurality of sending units that respectively send signals; a plurality of receiving units provided on a printhead and respectively corresponding to the plurality of sending units, the plurality of receiving units that receive signals via a signal line; and a phase adjustment unit that, based on a phase difference of a plurality of signals respectively received by the plurality of receiving units, controls and outputs a delay of the plurality of signals, wherein each of the plurality of sending units sends a phase adjustment signal for phase adjustment to be performed by the phase adjustment unit, and a phase adjustment signal sent by a first sending unit includes a signal having a coordinate phase and an opposite phase with respect to a phase adjustment signal sent by a second sending unit.

There is provided a server apparatus including a storage unit configured to store setting information used by a client apparatus to operate, a reception unit configured to receive, from a first client apparatus, a deletion request for deleting a part of the setting information from among the setting information stored in the storage unit, a notification unit configured to notify a second client apparatus of update information indicating that the part of the setting information for which the deletion request has been made is deleted, and a control unit configured to perform control in such a manner that the update information remains to be stored in the storage unit until a predetermined condition is satisfied after the deletion request is received, and is deleted from the storage unit in accordance with a satisfaction of the predetermined condition.

A communication control device includes a communication unit, a reception unit, and a controller. The communication unit transfers first image data obtained from a first processing device to an external control device for each portion among portions that are predetermined transfer units, and transfers second image data transferred from the external control device to a second processing device, the communication control device and the external control device being included in a system and being connected to each other via a communication line for half-duplex communication. The reception unit receives a signal that is transmitted during an interval between the portions of the first image data. The controller performs control so as to start obtaining the second image data transferred from the external control device in a case where the signal is received by the reception unit.

An image-reading device, such as optical code readers used in retail environments to scan objects, is configured to select from various operational modes. The operational modes are selected based on an application of the image-reading device, such as optical code identification or image recognition. Red, white, and other color light sources are activated in patterns corresponding to an illumination sequence of the selected operational mode, while imagers are activated to capture an image based on an exposure pattern of the selected operational mode. Further, a repeating series of light pulses having different portions of light is provided. Various imagers are configured to capture images over one of the portions. This allows an operator to perceive one continuous light pattern, yet allows various imagers to capture an image under different light conditions used for different applications of the image-reading device.
