Abstract
An inkjet printer comprises an inkjet printing head. The printing head has a reduced width in a main scanning direction, is compact, and assures improved printing quality. In the printing head, a head base plate has ink channels and nozzle rows. The ink channels and nozzles are in communication with pressure chambers. The nozzle rows are arranged in an inclined manner along a sub-scanning direction, and are arranged with spaces wider than a printing width in the sub-scanning direction. Different colors of ink are supplied to the ink channels so as to print images in colors such as yellow (Y), magenta (M), cyan (C) or black (BK).
