A plurality of forwardly extending tabs are spaced on a rear frame member and corresponding pockets with horizontal slots are similarly spaced near the rear edge of the bottom panel. The pin-fins are arranged with one or more turning openings and one or more guiding openings so as to direct the cooling flow towards the cooling holes. When the printer conducts gradation printing with using m kinds of waveforms selected from the n kinds of waveforms, a difference among the blocks in an amount of ejected ink per nozzle in a case of using the stored combinations of m kinds of waveforms for the respective blocks is smaller than that in a case of using one and the same combination of m kinds of waveforms for all the blocks. The start enrichment device has an operating position and at least one start position.
