Abstract
The print head 7 is designed to eject ink onto a recording head with a plurality of resolution degrees. A plurality of kinds of recording papers have different degrees of ink permeability. Accordingly, ink dots of different diameters can be printed on different kinds of papers. There is a possibility that the characteristic of the recording medium will not properly correspond to the resolution with which the print head 7 is controlled to print images on the recording head. In this case, the printed images will have a low quality. Accordingly, it is necessary to perform a trial printing many times. In order to save time and ink, a characteristic of the recording paper is judged, and the resolution, at which the print head 7 is to be controlled to print images on the recording paper, is selected dependent on the judged result. The printer 1 can therefore reproduce a high quality image and is good in its economical view. The CPU 11 receives image data from the external CPU 50. The resolution data memory 12a stores a resolution value which corresponds to a characteristic data obtained by the paper characteristic detector 16. The control signal conversion portion 20 converts the image data into a control signal for controlling the print head 7 to print the image data onto the recording medium at the resolution stored in the memory 12a.
