An information processing apparatus includes a first communication unit configured to communicate with a first communication apparatus; a second communication unit configured to wirelessly communicate with each of one or more second wireless communication apparatuses; an acquisition unit configured to acquire from the first communication apparatus via the first communication unit an apparatus ID that is held by the first communication apparatus and that is used for identifying one of the one or more second wireless communication apparatuses to or from which the second communication unit transmits or receives data; and a control unit configured to control the second communication unit to transmit or receive the data to or from the one of the one or more second wireless communication apparatuses that is identified by the apparatus ID acquired by the acquisition unit.

Information processing apparatus and wireless communication method

A printing apparatus includes a printer, a first wireless communicator, and a second wireless communicator. The first wireless communicator performs wireless local-area network (LAN) communication. The second wireless communicator transmits, to the information terminal, information required to perform the wireless LAN communication between the printing apparatus and an information terminal. The first wireless communicator receives print data from the information terminal. The printer performs printing based on the print data.

An image processing apparatus includes a first communication unit, an image processing unit, and an authentication unit. The first communication unit performs contactless communication using a radio-frequency identification (RFID). The second communication unit performs wireless communication. The image processing unit performs an image processing job. The authentication unit authenticates a user of the image processing apparatus. In a case where the authentication unit authenticates a user, the second communication unit starts the wireless communication with an external apparatus which has been identified by an identification (ID) communicated from the external apparatus. The image processing unit performs the image processing job using the wireless communication between the second communication unit and the external apparatus.

A printing system is operable to enable a printing apparatus to continue a printing of a print job by using printing media of a second supply source after using printing media of a first supply source without expending all of printing media of the first supply source. The printing media included in the first supply source are the same size and type as the printing media included in the second supply source.

Printing system, job processing method, storage medium, and printing apparatus

A printing apparatus performs printing with the use of sheets of paper set in any of a plurality of paper-feeding units. The print apparatus is controlled by a method including: determining whether the amount of sheets of paper remaining in a first paper-feeding unit has reached a predetermined amount; and if so switching from the first paper-feeding unit to a second paper-feeding unit. If it is determined that the amount of sheets of paper that remain in the first paper-feeding unit has reached the predetermined amount, control is performed so that the paper-feeding unit that is used for printing should be changed after the ejection of the last one of a plurality of sheets of paper that are included in one set thereof set in the first paper-feeding unit.

Printing apparatus, method for controlling printing apparatus, program, and storage medium

An image forming apparatus that forms images on sheets by using input image data, the apparatus including: a detection unit that detects a blank area outside of an image forming area formed on a sheet; a setting unit that, when a sum of a length in a conveyance direction of a blank area on a trailing edge side in the conveyance direction of a sheet and a length in the conveyance direction of a blank area on a leading edge side in the conveyance direction of a sheet conveyed following the sheet is a reference value or less, sets a sheet conveyance interval to the reference value, and when the sum is greater than the reference value, sets the conveyance interval to be less than the reference value; and a conveying unit that conveys the sheets at the conveyance interval set by the setting unit.

Image forming apparatus and method for controlling sheet conveyance intervals in same

A printing apparatus includes a CPU that determines whether or not to use operation information included in paper information received from another printing apparatus. If it is determined to use the operation information, the received paper information is registered as the paper information of Type 2. In addition, the CPU included in the printing apparatus selects one of a plurality of pieces of paper information and controls a printer unit such that the printer unit performs a printing process in an operating state based on the operation information included in the selected piece of paper information.

Printing apparatus and method for controlling the same in enabling use of paper information

Printing apparatus and method for controlling the same

An image processing apparatus enables efficient use of an image memory area according to processing contents set by a user. A CPU searches destinations set sequentially, and makes for each destination an image area information generating decision for searching for a destination that generates an image a printer section possibly output. After completing the image area information generating decision for all the destinations, the CPU decides whether the image area information is to be generated or not in the end. When it decides that the image area information is to be generated, it sets a compression rate of a compression expansion circuit of an image compression expansion section at a higher value, and simultaneously enables the output of the image area data buffer. When it decides that the image area information is not to be generated, it sets the compression rate of the compression expansion circuit of the image compression expansion section at a lower value, and simultaneously disables the output of the image area data buffer.

Image processing apparatus and method

An object of this invention is to provide a convenient printing system applicable not only to the office environment but also to the POD environment. To accomplish this, a printing system capable of supplying a print medium to a printing apparatus from a plurality of feeding apparatuses each having a feeding unit for feeding a print medium, a multi feed detection unit for detecting occurrence of multi feed of overlapping print media, and a multi feed discharge unit for discharging multi-fed print media includes a multi feed discharge destination setting unit for, when the multi feed detection unit detects occurrence of multi feed, setting which of multi feed discharge units is to accept multi-fed print media, and a control unit for controlling the feeding apparatus to discharge the multi-fed print media to the multi feed discharge unit set by the multi feed discharge destination setting unit.

Printing system and control method thereof

The present invention relates to image input/output apparatuses for outputting inputted image data, a control method of the image input/output apparatuses, an image input/output system and a storage medium thereof. According to the present invention, in case of receiving an image output request of outputting image data inputted by another image input/output apparatus using the another image input/output apparatus and an own image input/output apparatus, setting related to sheet size selection of the own image input/output apparatus is disabled, and data size of the image data transferred from the another image input/output apparatus is calculated. Then, output sheet size is selected on the basis of the calculated result.
