An image forming apparatus that is capable of wireless communication with an operation device and that can be operated by the operation device via the wireless communication, the image forming apparatus comprising:

Image forming apparatus

A communication apparatus includes a reception unit that receives a Bluetooth&#xae; beacon signal transmitted from a printing apparatus, an identification unit that identifies a reception field intensity of the beacon signal, a display unit that displays a reception screen for receiving a transmission instruction in a case where the identified reception field intensity is less than a first threshold and greater than or equal to a second threshold that is smaller than the first threshold, and a transmission unit that transmits, to the printing apparatus, an authentication request enabling a user to log into the printing apparatus in response to receipt of the transmission instruction.

Communication apparatus and control method for communication apparatus

When detection intensity by an object detection sensor is larger than a first threshold, a user is notified that the object detection sensor has detected an object. When detection intensity by the object detection sensor is larger than a second threshold which is larger than the first threshold, an image forming apparatus is recovered to a state capable of executing a function the image forming apparatus.

In a case where a power transmission device operating as a master disappears, a wireless power feeding system selects a power transmission device to operate as a master instead based on predetermined priority levels.

In case of deleting shingle-recorded data on a recording medium, it enables to completely delete the data with the number of writing times less than the number of writing times in data recording. To do so, a magnetic recording apparatus, which records the data on the recording medium in a first direction with a writing unit, controls movement of a relative position of the recording medium and the writing unit such that a quantity of the movement in a second direction perpendicular to the first direction in the data deletion by overwriting another data is larger than a quantity of the movement in the second direction in the data recording.

A print processing apparatus processes a print job that includes print data corresponding to a plurality of pages and first paper information relating to papers used in printing of the print data. The microprocessor unit sets second paper information relating to a paper stacking order of a paper stack including a plurality of types of papers placed in a mixed state in one paper feeding tray. Then, the microprocessor unit compares the first paper information with the second paper information. The microprocessor unit controls the printer based on an obtained comparison result so that the print data can be printed on a target paper on which the print data should be printed, and controls the printer based on the obtained comparison result so that any surplus paper other than papers that are necessary and sufficient can be separated from papers on which the print data has been printed.

Print processing apparatus, control method, and storage medium

An information processing apparatus includes a control unit that, in a case where it is determined that proxy response processing should be performed, performs control such that an inputted job is processed without causing the information processing apparatus to transition from a second power mode to a first power mode, and, in a case where it is determined that proxy response processing should not be performed, performs control such that inputted job is processed after causing the information processing apparatus to transition from the second power mode to the first power mode.

Information processing apparatus, method for controlling information processing apparatus, and program

An image forming apparatus includes a first communication processing unit and a second communication processing unit, which communicate with an external device, respectively. A power supply unit supplies power to the second communication processing unit and a switching unit switches from the first communication processing unit to the second communication processing unit as a communication destination of the external device, when the first communication processing unit receives data from the external device in a power-saving state where the power supply unit supplies power to the first communication processing unit and the power supply unit stops supplying the power to the second communication processing unit.

A special color specification area is subjected to inspection processing assuring that the special color specification area is higher in color reproducibility than an area other than the special color specification area.

Inspection apparatus, inspection method, inspection system, and storage medium

An image processing apparatus includes a microprocessor unit which acquires information about the attribute of a print job from the received print job, determines which method is suitable as a printing method for the print job, performs a first printing method in which a print process is started before a raster image processing (RIP) process on all pages included in the print job is ended or a second printing method in which a print process is started after the RIP process on all pages included in the print job is ended, based on the attribute information, and decides the printing method determined as suitable for the print job as the printing method to be executed on the print job.

Image processing apparatus, image processing method, and storage medium

A print system which are capable of inhibiting simultaneous use of the encrypted print and the box storage to thereby increase the security of print data. A host computer has an encryption function of encrypting print data, and issues a print job for the print data encrypted by the encryption function. A print server receives the issued print job, and has a decryption function of decrypting the encrypted print data of the received print job. A printer has a storage function of storing the print data decrypted by the decryption function, and outputs the stored print data. At least one of the host computer and the print server inhibits simultaneous use of the encryption function and the storage function.

Print system, control method therefor, information processing apparatus, control method therefor, program for implementing the control method, and storage medium storing the control program

An information processing apparatus connected to a printing apparatus via a network encrypts print data if identification information is input, and does not encrypt print data if identification information is not input. If identification information is input and the print data has been encrypted, the information processing apparatus sends a print job including the encrypted print data to the printing apparatus via the network; otherwise, the information processing apparatus sends unencrypted print data to the printing apparatus via the network.

Provided are an image processing apparatus and image processing method capable of processing image data as packet data, and compressing the image data in real time to a data amount within the storage capacity of a memory. Image data in the form of packet data is divided into a plurality of blocks by a block forming circuit (), and compressed at a first compression ratio by a DCT circuit (), quantizing circuit (), and Huffman encoding circuit () for each block. A counter () measures the data amount of the compressed image data. If the measured data amount is equal to or larger than a predetermined value, the image data stored in a memory () is recompressed at a second compression ratio as a higher compression ratio by a Huffman decoding circuit (), bit shifting circuit (), and Huffman encoding circuit ().
