A print control system for a color ink jet system printer includes a yellow print buffer, a magenta print buffer, a cyan print buffer and a black print buffer. Image information and character information are applied from a data processing apparatus to the print control system. The image information includes a color data and a pattern data. The image pattern data is introduced into a selected print buffer in accordance with the image color data. The character information includes a color data and a character code data. The character code data is applied to a pattern generator which develops a character pattern data. The thus developed character pattern data is applied to a selected print buffer in accordance with the character color data, whereby a combined pattern data is obtained in the print buffers. |

DETAILED DESCRIPTION Accordingly, an object of the present invention is to provide a color image printer which effectively prints out a combined character pattern, image pattern and background color.
Another object of the present invention is to provide a print control system in a color ink jet system printer of the ink-on-demand type, for effectively combining character patterns, image patterns and background color.
Other objects and further scope of applicability of the present invention will become apparent from the detailed description given hereinafter.
It should be understood, however, that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
To achieve the above objects, pursuant to an embodiment of the present invention, character code information is introduced from a data processing system into a control system of a color image printer, and the character code information is stored in a character buffer.
The control system includes a character pattern generator which develops a pattern signal in accordance with the character code information stored in the character buffer.
The control system includes four print buffers for storing the print data for yellow printing, magenta printing, cyan printing and black printing.
The pattern signal developed from the chatacter pattern generator is applied to one of the four print buffers in accordance with a color indicating data separately applied to the control system.
An image data is applied from the data processing system to the control system in addition to the character code information.
The image data is independently introduced into a selected print buffer, wherein the image data and the character pattern signal are combined with each other.
The combined pattern data stored in each of the four print buffers are applied to corresponding printer heads for conducting the yellow printing, magenta printing, cyan printing and black printing, respectively
