Abstract

PURPOSE:To make manufacturing easy and obtain a high gradation output by arranging each heat generating element at mutually different positions in the longitudinal direction of grooves and installing a heat generating element head and a guide member in such a manner that these can move relatively. CONSTITUTION:When a guide member 5 and a heat generating element head 1 are tightly connected and the guide member 5 is driven back and forth in an arrow direction at a required frequency and at the same time, ink is supplied to an ink fountain part 6, ink is always fed to a groove 4. Further, when a drive pulse is applied to any heat generating dot element 2, bubbles generate in a plurality of grooves 4 which correspond to the heat generating dot elements 2, and are ejected to recording paper to allow any printing. Consequently, when it is presumed that for instance, the ratio of x to y in a single dot z is 2:3, and the ratio of distance from the head edge 1a for heat generating elements 2a, 2b is 1:2, the ratio of ink ejection amount corresponding to the mentioned ratio of 1:2 is set as 1:3. In addition, 4X4=16 gradation can be output by hammering of the printing head 4 times for a single dot, and an output of 16X4=64 gradation can easily be obtained by combining four dots of the 4X4=16 gradation.
