A print system comprising:
- a relay device configured to communicate with a terminal device;
- and
- a print device coupled to the relay device by a cable, wherein
- the relay device
- supplies power to the print device via the cable, and
- when receiving a print instruction from the terminal device, generates print image data based on the print instruction and transmits the generated print image data to the print device via the cable, and
- the print device
- is driven by the power supplied from the relay device, and
- prints a print image indicated by the received print image data when receiving the print image data from the relay device.
A print device to be coupled, by a cable, to a relay device communicable with a terminal device, the print device comprising:
- a print unit;
- and
- a print device control unit configured to cause the print unit to perform printing with power supplied from the relay device via the cable, wherein
- the print device control unit
- receives, from the relay device via the cable, print image data generated by the relay device based on a print instruction from the terminal device, and
- causes the print unit to print a print image indicated by the received print image data.
A relay device communicable with a terminal device and to be coupled to a print device by a cable, the relay device comprising:
- a relay device control unit, wherein
- the relay device control unit
- supplies driving power to the print device via the cable, and
- when receiving a print instruction from the terminal device, generates print image data based on the print instruction and transmits the generated print image data to the print device via the cable.
