ABSTRACT:
A recording sheet is fed two times for recording of one line. Two recording operations corresponding to the respective sheet feeding operations are performed in a dispersive manner based on gradation data that are different for the respective sheet feeding operations. For example, binary data for the first and second recording operations are generated by comparing the gradation data with odd-numbered and even-numbered gradation reference values, respectively.
