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 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： An interface in accordance with IEEE 1284 has a signal output stage which is a totem pole circuit. The totem pole circuit may be damaged if its output signal line is left grounded for an extended period of time or if outputs are being delivered at both ends of the signal line. Drive by the totem pole circuit is limited to a case where a signal to be output is at a low level and to a length of time equivalent to, say, one clock period from the moment the signal makes a transition from the low to a high level. A high impedance is established at all other times during which the high level is in effect, with the high level being maintained by a pull-up resistor connected to the output signal line. As a result, the totem pole circuit will not be damaged even if the output line is grounded while at the high level.

摘要： A recording apparatus records an image on a recording medium by scanning by a recording head. Mask data for masking record data is set in registers, a record timing signal synchronized with the scan of the recording head is counted up by a counter, and the mask data set in the registers is selected by selectors in accordance with the count. The selected mask data is logically ANDed with the record data to drive the recording head. A load to software is reduced and the recording is attained while the record data is masked with a simple construction.

摘要： Image data developed on print buffers can be read at consecutive or adjacent addresses and transferred to recording heads at high speed. An I/F DMA block transfers image data to DRAM at discrete addresses to develop the image data on DRAM. Thereafter, a head DMA block reads the image data in DRAM at addresses consecutive in a mount direction of the recording heads and transfers the read image data to the recording heads.
