Abstract: An image forming apparatus includes a holding unit, a search unit, an update unit, and a transmitting unit. The holding unit holds group information including identification information of a different image forming apparatus belonging to a group to which the image forming apparatus belongs. The search unit searches for a candidate image forming apparatus to which the image forming information is to be transmitted at a predetermined timing when elimination of the image forming information is estimated. The update unit updates the group information such that the candidate image forming apparatus found by the search unit is included in the group. The transmitting unit transmits the group information updated by the update unit to the different image forming apparatus at the predetermined timing.

Abstract: An image forming apparatus includes a communication unit, a prohibition unit, an execution unit, and a control unit. The communication unit communicates with an external apparatus. The prohibition unit prohibits the communication unit from communicating with the external apparatus when a command for executing initialization with respect to the image forming apparatus is specified. The execution unit executes a process for accepting set information of the initialization when the prohibition unit prohibits the communication unit from communication with the external apparatus. The control unit executes a process for informing that the initialization should be executed when an elapsed time of a waiting state where input of the set information is not executed exceeds a given period.

Abstract: A control device includes a device state changing unit, a communication unit, a communication unit, a storage unit, a storage unit state changing unit, and a reducing unit. The device state changing unit changes a state of the control device between a power saving state and a normal state. The communication unit communicates with a controlled device. The storage unit is an object of at least one of reading operation and recording operation by the communication unit. The storage unit stores at least part of information which the communication unit needs for communication with the controlled device. The storage unit state changing unit changes a state of the storage unit between a stored content holding state and a normal state in given cycles. The reducing unit reduces frequency of operation of reading and recording to the storage unit in the communication unit.

Abstract: A printer device includes a bit map memory for storing bit map data of one character, an intermediate data generator, an intermediate data storing area, a development unit, and a printer. The intermediate data generator generates intermediate data having information representing the presence/absence of an edge line of a character and positional information of the edge line every dot-scan line from outline data consisting of coordinate value data. The intermediate data storing area updates and stores the generated intermediate data every dot-scan line. The development unit sequentially develops bit map data in the bit map memory every dot-scan line on the basis of the stored intermediate data. The printer prints the character on the basis of the bit map data of one character developed and stored in the bit map memory.
