Abstract
Abstract A color printing apparatus for deciding a printing color in accordance with a character group has: memories to store character patterns of the colors corresponding to the character groups of each respective color; an input device to input character codes and a character group selection code; a selector to select a predetermined character group on the basis of a character group selection code; a deciding circuit to choose a predetermined one of the memories to store the character patterns in accordance with the character group selected by the selector; a character pattern memory to store the character pattern corresponding to the character code; a developing circuit to develop the character pattern read out of the character pattern memory into the predetermined memory chosen by the deciding circuit on the basis of the input character code; and a printer to print the character pattern developed by the developing means by the color corresponding to the memory. With this apparatus, color printing can be easily performed by a simple construction without need for a complicated color control.
