  • Printing method and apparatus and printing system including printing apparatus
    Patent number: 6384921
    Abstract: A printing method and apparatus in which basic image data and information of the printing position of the image data on a recording medium are input from a data source and stored in advance, and the designated image data is bitmapped at the printing position to print an image, thereby increasing the printing speed, and a printing system including the printing apparatus. In this system, image data sent from a host is registered as a basic image, and the image is bitmapped in an image memory on the basis of the information of the printing position, of the stored basic image data on a printing paper sheet, sent from the host. The image data bitmapped in the image memory is then output to a printhead to print the image.

  • Ink-jet printing method and apparatus therefor, and printing system including said apparatus
    Patent number: 6338540
    Abstract: An ink-jet printing apparatus receives image data from a host computer and prints the image data. If an elapsed time from an end of printing processing for one printing job to start of printing processing for the next job is less than a predetermined time period, printing processing for the next job is started, without subjecting ink-jet heads to a recovery process, following the end of printing processing for the one job. The recovery process is carried out not only when the predetermined period elapses but also whenever processing for printing on a predetermined amount of printing medium is executed.

  • Image forming apparatus and method for selecting print heads especially for barcodes
    Patent number: 6236752
    Abstract: Upon reaction of data from a host computer, an image forming apparatus analyzes the data, and maps bitmap images onto corresponding image memories in accordance with the analysis result. When it is determined that the data includes a barcode image, non-barcode image data mapped on the black image memory is OR-mapped onto the cyan, magenta, and yellow image memories. The barcode image is mapped onto the black image memory to print.
