  • PRINTER SYSTEM
    Publication number: 20220274424
    Abstract: [Object] To provide a printer system that is simple in structure, and has dual-head capability or duplex printing capability as desired. [Solution] A printer system 1 includes a first printer unit 10, and a second printer unit 20. The first printer unit 10 includes a first-printer housing 10a, and a first thermal transfer part 13. The second printer unit 20 includes a second-printer housing 20a, and a second thermal transfer part 23. The first printer unit 10 and the second printer unit 20 are independent of each other and capable of connecting to each other. A sheet printing paper 2 printed on by the first printer unit 10 is sent to the second printer unit 20 and then continuously printed on by the second printer unit 20.
