Abstract

PURPOSE:To enable to almost halve the data amount in a character generator, by compressing a dot pattern of even and odd row adjacent to a dot matrix constituting one character into dot data corresponding to one row of dot pattern for expression. CONSTITUTION:The dot data corresponding to printed character and even and odd data are read out from the character generator 10, and they are respectively stored in the dot data buffer 11 and the even and odd data buffer 12. The output control circuit 13 receives the output of the buffer 12 as the control input, and among the effective dots included in 1st and 2nd row of the buffer 11, the effective dot to the column present in the odd number column is printed to the 1st column and the effective dot to the row present in the effective dot in only even number column is printed to the 2nd column, allowing to supply dot data to the head drive circuit 14. Similarly, dot data is delivered so that the effective dot can be printed to the 3rd or 4th column every row, the similar control is made to the 5th column on and after.
