  • Patent number: 6549301
    Abstract: In a color printer system which issues printing instruction from its host and performs printing by its printer, the host decides which case of the two following cases can more reduce a quantity of data transferred from the host to the printer; one being that the host performs an image transform and the other being that the printer performs the image transform, and thus decides which should perform the image transform, the host or the printer. When it is decided that the host should perform the image transform, the image transform processing is performed in the host, and information which indicates whether printing data transferred to the printer is the one before an image data transform or after the image data transform is added to printing data. The printing data to which the predetermined information is added is transferred to the printer.

  • Publication number: 20030027142
    Abstract: A novel transcriptome analyzing method and to provide a gene found by this method and a protein encoded by the gene. A method for determining whether or not a continued arbitrary DNA sequence existing in the genome of an arbitrary biological species, in which the nucleotide sequence is already known but its possibility of being a gene expression region is unclear (specific region), is the specific region, which comprises detecting whether or not a nucleotide sequence that corresponds to the nucleotide sequence of the region is present in the RNA of the biological species, and a method for determining the gene expression region in an arbitrary region on a genome or the entire genome, which comprises repeatedly carrying out the above method.
