Printing apparatus

A printing apparatus comprising:

• a printing head through which printing onto a printed medium is performed;
• a data analysis unit that analyzes a print job received from an external apparatus and outputs a printing command and a first set of image data;
• and
• an image process unit that performs image processing for converting the first set of image data into a set of printing data on the basis of which the printing onto the printed medium is performed,
• wherein the image process unit includes a program memory bus that communicably interconnects the data analysis unit and the image process unit and carries the printing command, a data memory bus that communicably interconnects the data analysis unit and the image process unit and carries the first set of image data, a program memory unit that stores therein a program for the image processing, a data memory unit that stores therein the first set of image data input from the data analysis unit, a color conversion process unit that performs color conversion processing on the first set of image data on the basis of the printing command and the program for the image processing, and a halftone process unit that performs halftone processing on a second set of image data resulting from the color conversion processing on the first set of image data, on the basis of the printing command and the program for the image processing, and
• wherein the image process unit performs the color conversion processing and the halftone processing in parallel.
