ABSTRACT:
A printer has a memory containing print information on a plurality of characters, grouped by a print pressure of the character, and a control unit for controlling the print pressure in accordance with the print information stored in the memory. The memory stores the print information for each print pressure group in ascending order. The duration of the impact pulse is determined once the character's code is found in the list of characters stored in order of lowest to highest impact energy, based on character size.
