Abstract: Disclosed are a laser printer for pathological embedding cassettes and a printing method thereof. The laser printer includes an ink jet cartridge (3) filled with pigment ink, where a conveyor belt (6) is disposed below the ink jet cartridge (3), the semiconductor laser (4) is disposed on a side of the ink jet cartridge (3), and a photoelectric sensor (10) for detecting the position of an embedding cassette (1) is disposed on the conveyor belt (6). The beneficial effects brought by the printer and the printing method thereof are as follows: 1. By ejecting pigment ink droplets on an embedding cassette and irradiating the ink droplets with a laser beam from a semiconductor laser, the ink droplets have a rapid increase in temperature and are cured, so that colors are applied on a plastic surface and can be easily recognized. 2. With a combination of a guide groove and a semilunar pushing wheel, the conveyance of the embedding cassettes is implemented effectively to facilitate an operator in picking up and placing the embedding cassettes. 3. The position of an embedding cassette can be directly precisely detected using a photoelectric sensor, so as to ensure the precise irradiation of the ink droplets by the semiconductor laser, thereby improving the curing quality.

Abstract: In an example implementation, an authentication system includes a printer having a controller and a memory. The authentication system also includes an authentication algorithm stored in the memory and executable on the controller to issue a cryptographic timing challenge, and to authenticate a print supply cartridge when the cartridge provides a challenge response corresponding to an expected response within an expected time window.

Abstract: A plurality of terminals are provided on a circuit board of an ink cartridge, and a plurality of lines are formed by contact portions of the plurality of terminals. In a first line among the plurality of lines, contact portions of two terminals for detecting attachment are arranged, and a contact portion of a power supply terminal is arranged therebetween. The first line may be located at a leading side when the ink cartridge is moved in a predetermined direction and is mounted on a printing device, or the first line may be the line closest to an opening of an ink supply port, or the first line may be the line closest to an ink supply needle.
