Self-walking type printing device

The invention relates to a self-propelled print device, which is applicable to printing images on a flat-plate recording medium and comprises a frame; an embossing shaft, arranged at the bottom of the frame, extending along the width direction of the frame and being provided with at least an embossing roller; a first shaft, arranged on the frame and extending along the width direction of the frame; a print head module, installed on the first shaft and driven by a motor to move to and fro on the first shaft along the width direction of the flat-plate recording medium; a transmission device, being capable of driving the print device to move along the length direction of the recording medium; and a linking mechanism, uni-directionally matching with the transmission device. By adopting one drive motor to realize the movement of the print head module in two-dimensional direction, the invention achieves simple structure and low cost.
