A method of printing device discovery includes, with a low energy wireless (LEW) device within the printing device, sending a number of announcement messages. The printing device is in a sleep mode. The method further includes waking up the printing device upon receiving a response to the announcement messages from a mobile computing device. An LEW connection is established with the mobile computing device. The method further includes creating a second non-LEW wireless connection between the printing device and the mobile computing device.

An image forming system includes a first information processing apparatus, a second information processing apparatus, and an image forming apparatus. The image forming system is capable of performing a process of transmitting PDL data acquired by the first information processing apparatus to the second information processing apparatus and, then, transmitting the PDL data to the image forming apparatus to use the PDL data for image formation and a process of transmitting the PDL data acquired by the first information processing apparatus to the image forming apparatus in response to a request from the image forming apparatus without transmitting the PDL data to the second information processing apparatus to use the PDL data for image formation.

An information processing apparatus includes a first processor and a second processor. The first processor is operable to perform first processing and second processing in one of a plurality of operating states. The operating states includes a normal state and a power-saving state. The power-saving state is a state in which the first processor consumes less power than the normal state. The second processor is operable to perform the second processing while consuming less power than the first processor does. The second processor detects the first processing that the second processor is not able to perform. The second processor also causes the first processor to transition from the sleep state to the power-saving state to perform the first processing when the first processor is in a sleep state in which a power supply is stopped.

A printing device 1 has a print unit 21 that prints; a storage unit 23 that stores identification information; and a communication unit 22 that wirelessly transmits a position correction signal S1 including identification information stored in the storage unit 23.

A printing apparatus includes a print engine and a first controller configured to generate a raster data from a print job and cause the print engine to perform a print process based on the raster data. The first controller includes a first core and a second core. The first core is configured perform an analyzing process of analyze a job control command included in the print job and the second core is configured to perform an RIP process of generating the raster data from a PDL command.

A method for controlling an image forming system includes a shifting process in which a wireless operation unit from a sleep state to a ready state; a connection process in which the wireless operation unit connects individually to each of a first image forming apparatus and a second image forming apparatus via wireless communication without a wireless LAN router in response to the shift of the wireless operation unit to the ready state in the shifting process; and a display process in which the touch panel display displays, side by side, a first return icon to return the first image forming apparatus to a ready state and a second return icon to return the second image forming apparatus to a ready state in response to the execution of wireless communication in the connection process.

A document processing system includes a power scheduling server configured to receive time-based usage data from a multifunction device. In response to receiving the usage data from the multifunction device, the power scheduling server analyzes the usage data and determines a power saving policy for the multifunction device. The power scheduling server transmits the power saving policy to the multifunction device. The multifunction device performs changes of operational state based on usage and in accordance with the received power saving policy.

A document processing system includes a print job queue management system configured to temporarily hold print jobs in the print queue during periods of light use, so as to maximize the amount of time that the document processing system spends in energy efficient low power modes. The print job queue management system compares print jobs in the queue with print job hold criteria and releases print jobs for printing when certain criteria are met, such as when a threshold number of documents or pages are in the print queue, if an incoming print job is designated as high priority print job to be immediately printed, or during particular times of the day that are designated as peak use times, which can be determined from historical data. A user can manually force a document to print from the user interface of the document processing systems.

An energy saving setting unit controls an image forming apparatus that makes a transition to a power saving state if a transition time passes without any prescribed operation in a normal state, and it includes: a unit for storing specific day information distinguishing a normal operation day and a specific day; an auto pattern updating unit determining the transition time in a normal operation day based on past operational status of the normal operation day of the image forming apparatus; a specific day pattern registering unit receiving and storing setting of the transition time of the specific day; and a switching unit, switching the state of conduction of the image forming apparatus using the transition time determined by the auto pattern updating unit and the stored transition time, on the normal operation day and on the specific day, respectively, based on the specific day information.

A method of controlling an image forming system, the method including: determining whether or not a connection state enabling communication between an image forming apparatus and a second operation device has been established, in a case where an instruction is issued from a first operation device to the image forming apparatus; and displaying, in a case where it is determined in the determining that the connection state has been established, on a display of the first operation device, a selection screen for selection of whether or not the image forming apparatus is to be allowed to operate according to the instruction.
