    摘要: The information to be recorded is divided into 8-bit long data words. Each data word is then converted to 14-bit long code word. The code words are sequentially connected with a one-bit merging bit inserted between the code words to define a code bit sequence. The run-length of 0s in the code bit sequence is limited to be between 2 and 11. The one-bit merging bit normally takes a bit value of 0, but is changed to 1 when any one of the T.sub.min control or T.sub.max control is applied so as to accomplish the run-length limitation. The T.sub.min control is applied when the adjacent bits on both sides of the merging bit are 1s. The T.sub.max control is applied when trailing P bits of a code word preceding the merging bit and leading Q bits of a code word following the merging bit are all 0s, provided that P+Q.gtoreq.11, and in this case, at least either one of the P bits and Q bits has a bit sequence of (00000), and the bit sequence (00000) is changed to (00100).

    摘要: A first cutter 130 (cutting unit) is provided between a color recording unit 120 (the first printing unit) and an overcoat recording unit 140 (the second printing unit). A portion whereon color printing is completed by the color recording unit 120 of a recording paper 200 (printing medium) is cut off by the first cutter 130 and detached. An overcoat recording unit 140 performs an overcoat process on the detached recording paper (printing medium strip). In parallel with this, the color recording unit 120 performs next color printing on the recording paper 200. This makes it possible to reduce a printing time in a printing device including a plurality of printing processes without deteriorating printing quality. Further, an useless paper feeding is eliminated by optimally arranging the color recording unit 120, the first cutter 130, the overcoat recording unit 140, and the second cutter 160, etc. in accordance with a size of a printing area.
