Printing information processing device, printing device, printing information processing method and printing system
In a printing process, an image quality identifier is referred to in a packet header of image data. It is determined whether the image quality identifier is ‘1’ or ‘0’, and when the image quality identifier is ‘1’ indicating a high-quality image, six color printing is set. When the image quality identifier is ‘0’ indicating a low-quality image, four color printing is set. Thus, six color printing is executed for an image read out by a scanner in the CCD technique while four color printing is executed for an image read out by a scanner in the CIS technique. Accordingly, it can be determined according to a simple standard such as kind of scanner.
