    Abstract: A color copier machine includes a conventional image scanner for scanning successive swaths of an original document into an image memory and a conventional high quality four-color inkjet printing mechanism for printing each swath as an array of pixels each covered with up to three types of ink (black and one color or three colors). A monotone image is scanned only once and subsequent copies are printed from the half toned data stored in the image memory. The first copy is printed while the scanner is scanning, with each 8-bit pixel in the scanned image being printed and stored as a 1-bit (on or off) pixel (in the half-tone image. Print time for subsequent copies is less than that required for scanning/printing the first copy because in at least the black-only printing mode of a typical inkjet printer, the time required to scan and process a single swath is more than the time required to print that swath.

    Abstract: A recording apparatus for recording input image data on a recording medium includes: a buffer memory for storing a plurality of lines of input image data as recording data; a recording section which can record on the basis of the recording data at different speeds; and a speed storage section storing a plurality of recording speeds at which recording is performed by the recording section, one of the recording speeds stored in the speed storage section being selected as the recording speed for the recording section in accordance with the amount of recording data stored in the buffer memory. That is, when the amount of recording data stored in the buffer memory is larger than a predetermined number of lines .alpha..sub.1, uniform-speed recording is performed at a first recording speed, and when the amount has become smaller than the number of lines .alpha..sub.1, uniform-speed recording is performed at a second, slower recording speed. When, afterwards, the amount of recording data in the buffer memory has become larger than a second predetermined number of lines .alpha..sub.2 (>.alpha..sub.1), the recording speed is switched back to the first recording speed, at which uniform-speed recording is performed, thereby making it possible to prevent deterioration in recording quality due to variation in the recording period of the input image data while using a small-capacity memory.

    Abstract: A digital copying apparatus produces a right reading image with an image reading unit co-mounted on a carriage with an image printing unit. After a width of a document is scanned, either bidirectionally or unidirectionally, and digitized, it is stored in a band memory buffer before it is printed on the next successive sweep. The digitized data stored in the band memory buffer may be processed while it is stored, prior to being printed.
