Abstract
A multicolor serial dot printer has memories for storing printing data, which memories number the same as the recording colors. A bar graph, for example, is printed in staggered patterns and numerals and the like are superposed on it. For printing in black and red, for example, the graph data to be printed in red is stored in a memory, while the numeral data to be printed in black is stored in another memory. A control section controls read/write operations of the printing data into and from the memories, and also controls the operation of a printer control section. Under the control of the control section, the printer control section drives ink jet nozzles to print in accordance with the printing data read out from the memories. The printed graph is easy to see, and printing paper sheets are saved.
