摘要： An ink jet printer has a specific unit that is capable of splitting a dot into a plurality of divisions. The arrangement of splitting an ejected ink droplet into a plurality of parts to create a split dot having a plurality of divisions at a plurality of different positions in one pixel advantageously decreases the quantity of ink per position. This reduces penetration of ink in the direction of the depth of printing paper. Under the condition of a fixed quantity of ink, the split dot has a greater total area than the area of a single dot and ensure a higher resulting expressed density. This arrangement ensures multi-tone expression without changing the total quantity of ink ejected in each pixel.
摘要翻译：喷墨打印机具有能够将点分割成多个部分的特定单元。将排出的墨滴分解成多个部分以在一个像素中的多个不同位置处产生具有多个分割的分割点的布置有利地减少了每个位置的墨水量。这减少了墨在印刷纸深度方向上的渗透。在固定量的墨水条件下，分割点的总面积比单点的面积大，确保更高的表达密度。这种布置确保了多色调表达，而不改变在每个像素中喷射的墨的总量。

摘要： A recess is formed in a surface confronting an actuator unit of an ink supply inlet forming substrate. When a flow path unit and the actuator unit are bonded together using a fusible film, thermally expanded air is released into the recess to thereby reduce pressure. Further, by arranging the recess at a position confronting a pressure generating chamber, an air layer formed by the recess is allowed to function as a vibration shielding member.
