An information processing device includes a processing unit configured to divide original image data for a larger number of channels Nb than the number of channels Na into a plurality of groups so that a number of channels of each of the groups becomes no larger than the number of channels Na, generate compressed image data for the Na channels according to the processing unit from the original image data included in each of the groups, and generate the print command including the compressed image data for the Na channels corresponding to each of the groups, and a communication unit configured to transmit the print command to the printer.

Printing system having printer with chip for generating image data and information processing device for dividing original image data for a larger number of channels into groups

A recording medium determining device includes a light irradiating portion that irradiates a recording medium with visible light; a regular reflection light receiving portion that receives regular reflection light regularly reflected by the recording medium irradiated with light from the light irradiating portion; a diffused reflection light receiving portion that receives diffused reflection light diffusely reflected by the recording medium irradiated with light from the light irradiating portion; and a determining portion that determines the type of recording medium on the basis of each light amount of two or more visible light components with different wavelengths to one another among the light components received by the regular reflection light receiving portion and each light amount of two or more visible light components with different wavelengths to one another among the light components received by the diffused reflection light receiving portion.
