PICTURE DATA RECORDING APPARATUS

摘要

A recording apparatus in which recording is made several times each line in a partitioning manner part after part on each recording line for which there exists picture data to be printed. The system determines whether there exists picture data to be printed on each line or not. A sub-scanning speed per line is set such that when the determination is made that one or more successive lines immediately before a recording line for which there exists picture data to be printed is or are an entire blank line or successive entire blank lines for which there exists no picture data to be printed, the sub-scanning speed for the entire blank line or successive ones of the successive entire blank lines adjacent to the recording line is selected to be substantially equal to that at the recording line. The sub-scanning speed of other entire blank line or lines for which there exists no picture data is selected to be a speed which is sufficiently higher than that for the recording line.
