    Abstract: 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 (21) or electronically inputted to the host (21) 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 (1708) (EEPROM) in accordance with the discriminating result. The printhead (IJH) is controlled in accordance with the characteristic information written into the non-volatile memory (1708) to execute a print process.

    Abstract: An image communication apparatus for receiving image data includes a first detector for detecting a first line synchronizing signal for one-dimensional codes in the received image data and a second detector for detecting a second line synchronizing signal for two-dimensional codes in the received image data. The apparatus counts the number of detected second line synchronizing signals in accordance with a detection by said first detector, and determines a quality of the received image data in accordance with that number of the second line synchronizing signals. In particular, the apparatus counts the number of the second line synchronizing signals detected between one first line synchronizing signal and a next first line synchronizing signal.

    Abstract: PROBLEM TO BE SOLVED: To provide an output control circuit which can make any output terminal output an arbitrary internal signal and can monitor many internal signals even when the circuit has a small number of output terminals. SOLUTION: A monitor output control section 5 provided in a large-scale integrated circuit has five internal signal monitoring circuits 51, 52, 53, 54, and 55 to which the internal signal groups of their corresponding buses S1-S5 are inputted. The circuits 51-55 have the same circuit configuration. For example, the circuit 51 selects a prescribed bus from among the buses S1-S5 by means of a bus selecting register 518, performs logical operation on signals selected by means of a signal selecting register 519 by using one of logical and arithmetic circuits 512-516 corresponding to the selected bus, and outputs signals obtained as a result of the logical operation to a monitor output line S7 at the time of selectively outputting internal signals to the line S7.

    Abstract: PROBLEM TO BE SOLVED: To correct a landing position deviation due to a velocity change by a simpler method in real time. SOLUTION: At recording by scanning over a recording medium a carriage on which a recording head for discharging ink for recording is mounted, position information in a scanning direction of the carriage is generated by an encoder, and a discharge signal for instructing the recording head to discharge ink is generated on the basis of the position information. For example, when a scanning speed of the recording head changes by a period 6 because of cogging of a driving motor or the like, a discharge timing is delayed at a section 4 where the speed is lower than a reference speed, and a discharge timing is advanced at a section 5 where the speed is higher than the reference speed. Ink discharged from the recording head is thus landed to a desired position of the recording medium P.

    Abstract: PROBLEM TO BE SOLVED: To reduce the number of signal wires required for block division driving of a recording head. SOLUTION: A shift register 4 houses a printing date IDATA simultaneously with a transfer clock DCLK. A latching circuit 3 temporarily holds a bit data which is the same as the shift register 4 corresponding to a data latching signal DLAT. A shift register 6 houses a block data BDATA simultaneously with a transfer clock BCLK. A latching circuit 5 temporarily holds a bit data which is the same as the shift register 6 corresponding to a block data latching signal BLAT. A block selecting signal form a printing block selecting part 50, a printing data selection signal corresponding to a printing dot from a printing data supplying part 40, and an electricity charging time selecting signal are input to the AND gates 2-1, 2-2, 2-3, 2-4,...2-n and each output of the AND gates 2-1, 2-2, 2-3, 2-4,...2-n turns on/off a switching tansistor Tr. As a result, heaters 1-1, 1-2, 1-3, 1-4,...1-n are heated and ink droplets are ejected.
