    摘要: This invention provides a low-cost, economical printing apparatus and printing system. For example, characteristic information of a printhead which is described, printed, adhered, or formed on a printhead or its accessory (e.g., a packaging paper box) in a format identifiable to human or an electronic device is man-machine-interactively inputted to a host or electronically inputted to the host by a barcode reader or the like. The printing apparatus discriminates whether or not a command sent from the host via an interface is a command that includes characteristic information of the printhead, and control is made to write the characteristic information of the print head into a non-volatile memory (EEPROM) in accordance with the discriminating result. The printhead is controlled in accordance with the characteristic information written into the non-volatile memory to execute a print process.

    摘要: A parent node transmits a third specific message to child nodes as a broadcast message if a first specific message indicating the start of the child node collides with another message so that normal receiving cannot be performed. Then, the parent node sequentially transmits second specific messages to each child node and then receives responses to recognize the states of the children nodes. The parent node transmits a specific message indicating a realization of a sleeping state as a broadcast message to the children nodes, followed by transmitting a specific message when data to be transmitted from the child node has been generated. The parent node cancels the sleeping state when it receives the specific message.

    摘要: A recording head has a plurality of recording elements which are divided into a plurality of blocks and each block is driven in a time division fashion. The recording head has a signal generation circuit for generating an output signal for selecting a drive block in response to an input signal for designating the drive block from a main body of a recording apparatus. The number of signal lines of the input signal is smaller than the number of signal lines of an output signal. One such recording head is provided for each of a plurality of colors to record a color image. Signal lines of an input signal are common to the respective recording heads. Thus, the number of signal lines between the recording heads and the main body of the recording apparatus is reduced and cost reduction and space saving are attained.

    摘要: A command information transfer method and system capable of transferring command information by discriminating it from data information, and capable of using protocols of IEEE P1284, when a nibble or byte mode is incorporated which is stipulated by IEEE P1284 as bi-directional parallel I/F. A new communication mode simulating the extensibility link is set by an extensibility request value undefined by IEEE P1284 and command information is transferred at the second and following bytes of such multiple-byte negotiation. An nFault signal is used for both a notice of error and for a reverse direction information transfer request.

    摘要: A communication apparatus transmits a test message in one direction by the transmitting unit having narrow directivity capable of changing the transmitting direction, and an indication message which indicates that the test message is being transmitted by a transmitting unit having non directivity. Accordingly, the indication message is transmitted at least to the communicating party's apparatus. Subsequently, the transmitting direction of the test message is sequentially changed, and a similar process is performed. When the communicating party's apparatus detects a reception of the indication message, information indicating a level of the test message is transmitted to the transmitting apparatus as a response. The communication apparatus at the transmitting side detects the direction where the communicating party exists by receiving the information indicating the level. Hereinafter, the information communication is performed to adjust the transmitting unit of narrow directivity to the determined direction.

    摘要: An elastic memory determines an amount of delay of input data relative to other input data according to a phase difference between synchronous pulses each indicating a header of a frame of the associated input data. The elastic memory thus synchronizes both input data in the channel level. Both input data are time-division multiplied by a first multiplier. On the other hand, each counter receives synchronous pulses and thereby counting up to make a ROM produce address value of which order is determined previously according to the counted value. These address values are multiplied by a second multiplier. A decoder controls a RAM, a high-impedance control unit and a flip-flop to write in and read out of the RAM the input data. The read data are divided by a signal restoring device.
