Color plotter

摘要

A color plotter capable of printing out alphanumeric characters and the like at a high speed in addition to color plots is disclosed. A print head assembly comprising ink ejection heads is partly allocated to multicolor plots and partly to single-color characters and controlled to selectively print out graphic data and character data on a sheet as desired. The print head assembly is mounted on a carriage. In a plotter mode, the carriage and sheet are driven each in a reciprocal movement in directions perpendicular to each other with the plot section of the print head assembly energized. In a printer mode, the character section of the print head assembly is energized in response to input pixel data while the carriage is stroking.
