Abstract: A centralized queue for a network printing system is provided for allowing clients of a network printer to make job requests and enter a spot in a job queue without transmitting the actual print job data to the network. More particularly, an imaging device protocol (IDP) is provided which operates independently of the network layers below and only requires that a transport protocol/port be bidirectional. A wide variety of heterogenous network protocols may be supported by IDP for placing all of the incoming print job information in a print queue regardless of the protocol. Print job information from both IDP and non-IDP protocol/ports may be placed in the print queue by emulating IDP on the non-IDP protocol/ports. As a result, job information for all of the print jobs attempting to access a busy printer may be stored in the print queue so that the print jobs can be printed by the printer with a fair arbitration once the network printer becomes available.

Abstract: Disclosed is a wireless communication device adapted to receive a radio frequency signal containing a uniform resource identifier (URI) specifying a location of content on a server of an Internet content provider. The device is operable to transmit the URI to the server via a mobile telephone network and receive content transmitted by the server in response to reception of the URI, and to generate a GUI of which a frame includes a selectable image element representative of the Internet content provider. Also disclosed is a computer program executable by such a wireless communication device to cause the device, in response to reception of a URI, to generate a GUI of which a frame includes a selectable element representative of an Internet content provider.

Abstract: A network printing system for enhancing two-way communication between host computers and printers connected to a network. More particularly, the network printing system provides an imaging device protocol (DP) which enables various network service protocol/ports for host computers to communicate with the printer by "seamless plug and play" connectivity. IDP operates independently of the network layers below and only requires that the transport protocol/port be bidirectional. IDP allows all of the incoming print job information to be placed in the print queue regardless of the protocol for a wide variety of heterogenous network protocols. As a result, the network printing system enables print jobs from host computers connected to the network by a wide variety of heterogenous network protocols to be fairly arbitrated at the printer.

Abstract: An architecture for a network printing system is provided that allows the network printer to achieve and enhance two-way communication between the host computers and the printer connected to the network. The architecture layers provide a normalized interface to the layers below so that all of the protocol/ports interact in the same way. More particularly, an imaging device protocol (IDP) and an IDP emulator enable various network service protocol/ports, both IDP and non-IDP ports, to communicate with the network printer by "seamless plug and play" connectivity. Furthermore, this architecture allows host computers to request network printer services through a client service connection protocol (CSCP) and IDP when these protocols are supported and emulates CSCP/IDP interactions when the network services do not support the CSCP/IDP protocols so that print job requests may be executed from the same print queue.

Abstract: A printing system for producing prints from a job represented by a stream of image data written in a page description language and having a token expressed as a plurality of bits. The stream of image data is generated by and transmitted from an image data source. The printing system comprises an input section, communicating with the image data source, for receiving the stream of image data. The input section includes an arrangement for reading a block of image data to determine the presence of the token in the block of image data. An area, communicating with the input section, is adapted to store the stream of image data. An arrangement, responsive to the reading means determining the presence of the token, is adapted to initiate a selected operation in the printing system after the input section receives a potion of the stream of image data. A parser, communicating with the storage area, is adapted to parse the stream of image data to separate the stream into a plurality of image-related components.

Abstract: An electronic reprographic system with a scanner for scanning the document pages of a job and converting the document images scanned to an array of binary pixels. The ability to convert a high resolution array of binary pixels representing the scanned image to a lower resolution, gray version for display on a screen and further eliminate effects of contouring and moire on the displayed image.
