ABSTRACT:
The printing apparatus of the present invention includes a print head that has basic-color nozzle arrays and a specific nozzle array disposed in a staggered manner in relation to a black ink nozzle array, which is one of the basic-color nozzle arrays. The specific nozzle array can receive a solution independently of the basic-color nozzle arrays, and the solution can be selected from a plurality of solutions (including black ink) by selecting a specific cartridge mounted in a ink feeder. Images can be printed in black and white at a high speed with the aid of the two nozzle arrays (black ink nozzle array and specific nozzle array) by selecting black ink for the solution. Higher picture quality can also be obtained during photographic printing by selecting, for example, a dark yellow ink or a gray ink as the solution.
