  • Patent number: 7107058
    Abstract: A printer that enables a determination whether a failure has occurred in a device during initialization or a radio wave condition is bad. Receive electric field strength during a time period from a time at which a turn-off message is outputted to a time at which turn-on message is outputted and receive electric field strength after the turn-on message is outputted are measured. The measurements are compared with each other and information indicating the condition of each of a plurality of channels is printed out according to the results of the comparison. A user can reference the printed information to determine whether a failure has occurred in a device or the radio wave condition is bad.

  • Patent number: 7106472
    Abstract: A print driver is provided for use in printing a document from a computing device to an extended printing device are provided, the extended printing device being based upon a base printing device. The print driver typically includes a base module configured to process at least one print operation involving printer-specific attributes of the extended printing device that are shared with the base printing device, and an interface module configured to enable an extended module to be added to the print driver to process at least one print operation involving printer-specific attributes of the extended printing device that are not shared with the base printing device.

  • Patent number: 7099039
    Abstract: A system and a method to control the motion of envelopes within a postage printing module to accommodate the use of slower print techniques and to achieve high throughput in a mail processing system. Envelopes transported in a mail processing system are diverted into two or more parallel print paths. At the parallel postage printing modules envelopes are processed according to a motion profile in which the envelope is decelerated from a transport velocity to a slower printing velocity. After the printing operation has been completed, the envelope is accelerated back to the transport velocity and transferred to a downstream module, where the parallel print paths are merged back into a single print path. The print head is preferably geared to operate in synchronism with the print transport.

  • Patent number: 7079267
    Abstract: Provided are an image processing apparatus, method, computer program and recording medium capable of embedding a large quantity of additional information in image information upon dispersing the information in such a manner that it will not be noticeable visually. An error correction code is calculated from additional information [x(i)] to be added to image information (D1), and multiplexed information [y(j)] in which the error correction code has been added to the additional information is generated by an error correction encoder (13). Next, the bit sequence of the multiplexed information [y(j)] that has been generated is rearranged into a prescribed bit sequence by a shuffling unit (14), whereby multiplexed information [z(j)] is generated. Furthermore, the multiplexed information [z(j)] whose bit sequence has been rearranged is embedded in the image information (D1) by an additional-information multiplexer (15), whereby image information (D2) is generated.
