ABSTRACT:
A method of magnifying bit map font data used in printing by a dot matrix printer, in a horizonal direction. In a first step, a number of successive "0's", in a portion of the original bit map font data, which portion represents a solid line in the horizontal direction, is reduced to not more than a predetermined number by replacing each of one or more of the "0's" in that portion with a "1", so that the number of successive "0's" in that portion is not more than the predetermined number of successive "0's".
