A settlement system comprising:

• a receipt printer including a fourth controller;
• an information processing device including a fifth controller;
• a first terminal device including a first controller;
• a second terminal device including a second controller;
• and
• a third terminal device including a third controller, wherein
• the first controller of the first terminal device acquires customer identification information and transmits the customer identification information to the receipt printer,
• the fourth controller of the receipt printer transmits the received customer identification information to the information processing device,
• the fifth controller of the information processing device determines, based on the received customer identification information, that an electronic receipt was selected,
• the first controller of the first terminal device generates printing data and transmits the printing data to the receipt printer,
• the fourth controller of the receipt printer transmits the received printing data to the information processing device, and
• the fifth controller of the information processing device generates electronic receipt information based on the received printing data, and transmits the electronic receipt information when receiving an electronic receipt request from the third terminal device.

A receipt system comprising:

• a receipt printer including a fourth controller;
• and
• an information processing device including a fifth controller, wherein
• the receipt printer is capable of communicating with the information processing device and a first terminal device,
• the information processing device is capable of communicating with the receipt printer, a second terminal device, and a third terminal device,
• the fourth controller of the receipt printer receives printing data from the first terminal device and transmits the printing data to the information processing device, and
• the fifth controller of the information processing device generates image data based on the received printing data and transmits the image data to the second terminal device and, when receiving first selection information from the second terminal device, determines, based on the first selection information, that an electronic receipt was selected and generates electronic receipt information and transmits the electronic receipt information when receiving an electronic receipt request from the third terminal device.

A method of controlling a receipt system including a receipt printer and an information processing device, wherein

• the receipt printer is capable of communicating with the information processing device and a first terminal device,
• the information processing device is capable of communicating with the receipt printer, a second terminal device, and a third terminal device,
• the receipt printer receives printing data from the first terminal device and transmits the printing data to the information processing device, and
• the information processing device generates image data based on the received printing data and transmits the image data to the second terminal device and, when receiving first selection information from the second terminal device, determines, based on the first selection information, that an electronic receipt was selected and generates electronic receipt information and transmits the electronic receipt information when receiving an electronic receipt request from the third terminal device.
