摘要：Printhead structured such that printing elements are divisionally driven in unitof plural blocks, comprises: an input terminal to which printing data and encoded blockdata are serially inputted; a shift register sequentially shifting and storing one bit at a

time the data serially inputted from the input terminal; a latch temporarily storing thedata stored in the shift register; a decoder decoding the block data stored in the latch;and an AND circuit. The decoder outputs a signal in which encoded block data is partiallydecoded, and the AND circuit determines blocks to be driven based on the partiallydecoded signal. This structure enables to reduce an area of a printhead substrate,thereby enabling cost reduction of a printhead.
