摘要:
Provided are a printing device, an information providing system, and a printing method each capable of properly printing a dispersed image where information for specifying a plurality of websites is dispersed and human-readable information regarding each of the websites, and a printed matter obtained therethrough. A dispersed image generation unit (27) subjects ID pattern for designating a plurality of websites in a data storage unit (26) to inverse Fourier transform to disperse the ID pattern, and divides an image generated by the dispersion into the number equal to the plurality of websites, to thereby generate partial images. A printing unit (28) prints each partial image so as to be superposed on human-readable information such that multiple pieces of human-readable information in the data storage unit (26) can all be printed.

A thermal head and a thermal head unit are provided, which can prevent density variation while suppressing the size of the thermal head to be small. In a thermal head (10) having a head chip (20) having one surface on which heat generating elements and segment and common electrodes connected to the heat generating elements are provided, and an IC chip (32) connected to the segment electrodes, the common electrode (27) provided to the head chip (20) is elongated in an array direction of the heat generating elements, and connections between the common electrode (27) and common electrode wirings (41) are provided at plural locations along the array direction.
