A character pattern generator for a dot-matrix type printer. A storage device stores first dot pattern data for fixed pitch printing and second dot pattern data for proportional printing where the proportional printing dot pattern data corresponding to a character differs from the corresponding characters fixed pitch print data. A first address location pointer indicates the addresses of the fixed pitch dot pattern data in the storage device. A second address location pointer indicates the addresses of the proportional printing data in the storage device. A selector coupled to the storage device and the first and second address location pointers receives a character code signal and an attribute signal indicative of one of the fixed pitch and proportional pitch printing modes and supplies the character code signal to either the first or the second address location pointer in accordance with the attribute signal. |
