  • Patent number: 11399102
    Abstract: A print information processing system includes a terminal device, and a server. The terminal controller controls an image capturing device to capture an image representing at least part of a cassette and acquiring the captured image. The cassette accommodates print medium therein. A server storage stores information concerning a specific content including at least one of print data and information available for editing the print data. The system performs a detection process detecting the cassette by analyzing the captured image and a determination process determining whether the detected cassette satisfies a specific condition. The server controller performs an information transmission process transmitting the information concerning the specific content to the terminal device in a case where the determination process determines that the detected cassette satisfies the specific condition.
