Printers or printer controllers supporting wireless printing, or printing over air, are herein disclosed and enabled. The printer or printer controller may include wireless communication circuitry to facilitate a client to discover the printer. Subsequent to being discovered by the client, the printer may wirelessly transmit at least part of an output device profile to the client that has discovered the printer or the printer controller, the output device profile includes information related to the printer. After the printer is selected or identified for service, the printer may receive, from the client, print data that is based, at least partly, on the output device profile. A device specific driver may or may not be necessary for printing. The device discovery may be a short range wireless communication or local area network communication. The wireless communication circuitry may support at least part of IEEE 802.11 standards or Bluetooth specifications.

An output system, such as a wireless speaker or an Internet appliance, that supports voice activated commands is herein disclosed and enabled. The output system is wirelessly connectable to a service operated over a network (e.g., Internet) for receiving output data (e.g., music) from the service for outputting at the output system. The setup of the output system includes: (1) wirelessly discovering the output system using a smart phone, (2) establishing a wireless communication link between the smart phone and the output system (e.g., via Bluetooth or IEEE 802.11), and (3) providing information, such as security and/or authentication information, from the smart phone to the output system over the wireless communication link. Thereafter, the output system accesses the service operated over the network, and the outpt system is operabke to receive voice activated commands from a user while the output system is connected to the service.

Wireless devices that establish a wireless connection with a mobile device (e.g., smart phone) by wirelessly detecting the mobile device within a physical proximity, are herein disclosed and enabled. To set up a wireless device (e.g., Bluetooth devices, audio output devices, television controllers, Internet appliances, digital cameras, etc.) for connecting with a smart phone, the wireless device and the smart phone are simply placed within physical proximity of each other for short range wireless detection. During the wireless detection, the smart phone and the wireless device may exchange, transmit, or receive device or security information to facilitate future wireless connections. Subsequent to the short range wireless detection, the wireless device and the smart phone are connected or locked for future wireless communications (e.g., Bluetooth or IEEE802.11), and future wireless connections between the wireless device and the smart phone can be established without having to repeat the short range wireless detection.

Output devices supporting wireless device discovery are herein disclosed and enabled. To setup an output device for wireless connection, wireless device discovery is performed by a client of the output device to discover the output device. Upon being discovered, the output device may provide identification or information related to the output device to the client for establishing a wireless connection. Subsequently, the output device may receive, via the established wireless connection, digital content from the client for output. Wireless device discovery operations may be based on one or more of a close proximity wireless communication, a Bluetooth wireless communication, or a wireless communication compatible with a protocol within IEEE 802.11 standards. Security information or authentication may be required for establishing the wireless connection. Subsequent to having established the wireless connection, the output device receives the audio or video content from the client for playing at the output device.

A wireless device that includes at least a wireless communication unit, which is compatible with at least a protocol within IEEE 802.11 standards, for establishing a wireless connection with a server over a network is herein disclosed and enabled. To connect the wireless device with the server, the wireless device may first establish short range wireless communication with a client device, such as a smart phone. The wireless device may exchange data or information with the client device via the short range wireless communication; and the wireless device may implement an authentication procedure for detecting authentication information. Thereafter, the wireless device connects to the server over the Internet for accessing a service provided by the server. The accessing of the service may require authentication information on the wireless device, and the accessing of the service is subsequent to the wireless device having implemented the authentication procedure at the wireless device.

A bitmap processing system for creating digital documents on a digital printing press by a fulfiller includes a fulfiller operated raster image processor that receives customer application Page Description Language (PDL) job files containing information for creating the digital documents and generates bitmaps in accordance with the files and a fulfiller operated editor that modifies the bitmaps so that the resulting documents process more efficiently in production steps downstream of a printing process.

A printing apparatus is provided with a plurality of analyzing units, and a control unit. Each of the plurality of analyzing units analyzes each of different pages of print data, and notifies an error in a case that an analysis error occurs. The control unit receives the error notification from the analyzing unit, at which the analysis error occurs, among the plurality of analyzing units. And, the control unit notifies a cancel to another analyzing unit at which the analysis error does not occur. The control unit is further configured to notify, on a condition that a printing of all pages before a page at which the analysis error occurs is completed, the cancel to the another analyzing unit.

Output systems (e.g., information apparatus, Internet appliances, information pads, smart phones, audio output devices) supporting voice commands for playing digital content received from a service provided over a network (e.g., Internet) are herein disclosed and enabled. The output system may include an interface (e.g., touch sensitive screen interface, wireless interface) for receiving authentication information to access the service over the network. The service may be a subscribed service. While connected to the service, the output system receives voice commands from a user for outputting or playing digital content, and, in response to the voice commands, the output system receives, from the service, output data related to the digital content for outputting or playing at the output system. The output system may include a digital camera for image acquisition and may further be Bluetooth enabled for wirelessly receiving audio data (e.g., music) from a mobile device.

An image processing system includes a server to control a plurality of processes performable in the image processing system, a first image forming apparatus communicable with the server, and a second image forming apparatus communicable with the server. The server includes a first memory to store first image processing data, and a first processor to generate first image drawing information based on the first image processing data. The second image forming apparatus includes a second memory to store second image processing data, a second processor to generate second image drawing information based on the second image processing data, and a print engine to perform the image forming operation of the second image forming apparatus based on the second image drawing information.
