ABSTRACT:
A printer in which print densities of print heads can be adjusted simply and rapidly and set to have an optimum impact force, and a method of adjusting a print density are provided. Concretely, print density patterns which can be set at regular steps toward the high and low density sides of a predetermined density are generated. On the basis of the print density patterns, printing is conducted on a recording medium. A pattern in which a desired print density appears is selected and the print densities of the print heads are absolutely or relatively adjusted.
