ABSTRACT:
A print control system for a word processing apparatus includes a character pattern data generation circuit and a background pattern data generation circuit. The character pattern data developed from the character pattern data generation circuit and the background pattern data developed from the background pattern data generation circuit are combined at an OR gate. A composite data signal developed from the OR gate is applied to a dot matrix printer, whereby the character pattern is superimposed on the background pattern in order to ornamentally emphasize the character pattern.
