ABSTRACT:
An ink jet system printer has a printer head on which a plurality of orifice groups are provided in the main scanning direction of the printer head to correspond to various color inks, the orifices in each group being spaced by a specified distance away from one another in the sub-scanning direction. One of the plurality of the orifice groups consists of a larger number of orifices than the rest and all the orifices in the larger group are vertically aligned with the specified space therebetween. For character printing, the larger orifice groups is selected so that characters of higher definition are printed out at a higher speed. Thus, the ink jet system printer can be used for multiple purposes such as color figure printing and character printing.
