PURPOSE:To unify the length of black and white colors with simple constitution by controlling suitably the counting of a counter to control a broken length when the segment data parallel in the X or Y direction of a frame memory and the segment data where writing coordinates are shifted, are written. CONSTITUTION:A CPU 1 receives the data from an external host computer 2 through an I1F 3 and writes the data to a frame memory 4. The data stored into the frame memory 4 are read to a printer output circuit 7. A vector calculating circuit 8, the printing data of the broken line are transmitted from the host computer 2, changes over the black and white colors of the broken line. When the segment data parallel in the X or Y direction of the frame memory 4 are written, the counter to control a broken line length counts one by one, and when the segment data are written in which the writing coordinates are shifted in both directions of X and Y, the counting is executed by about 1.4 each. |
