US 11,504,976 B2 · Mobile printer

Abstract

According to at least one embodiment, a mobile printer includes a casing, a sensor, a print head, an interface, a controller, and a decolorizing device. The casing includes a power supply. The sensor detects the movement of the casing. The print head discharges ink containing a thermochromic colorant. The interface acquires image data. The controller discharges the ink from the print head based on the image data acquired by the interface and the movement of the casing detected by the sensor. The decolorizing device is coupled to the casing and includes a translucent film in which heat is generated by an applied voltage and a translucent substrate that is heated to a temperature at which the thermochromic colorant is decolorized by the heat generated in the translucent film.
