Image output system, information processing device, and authentication device

An image output method using an information processing device instructing an image output device to output an image, comprising;

• capturing, by the information processing device, an image of code pattern including device information specifying the image output device;
• obtaining the device information from the image of code pattern by the information processing device;
• obtaining user information specifying a user by the information processing device;
• outputting the device information and the user information to an external device by the information processing device;
• and
• receiving a result of image output processing by the image output device and displaying the result, by the information processing device.

An image output device instructed to output an image using an information processing device, the information processing device capturing an image of code pattern including device information specifying the image output device, obtaining the device information from the image of code pattern, obtaining user information specifying a user, and outputting the device information and the user information to an external device,

• wherein the image output device comprises a processor configured to:
• execute image output processing instructed by the user authenticated based on the user information when specified based on the device information obtained by the information processing device;
• and
• transmit a result of the image output processing to the information processing device.
