Communication method, non-transitory computer-readable storage medium storing program, and communication system

A non-transitory computer-readable storage medium storing a program to be executed by a computer serving as a transmission device configured to transmit document data constituted by a plurality of pages, the program comprising:

• generating a first divided data element and a second divided data element by dividing the document data into predetermined units;
• generating a first thumbnail image data element in accordance with the generated first divided data element;
• transmitting the generated first thumbnail image data element;
• generating a second thumbnail image data element in accordance with the generated second divided data element;
• transmitting the generated second thumbnail image data element;
• and
• after transmitting the first thumbnail image data element, starting transmitting the document data.

A communication system comprising:

• a server;
• a transmission device configured to transmit document data constituted by a plurality of pages to the server;
• and
• a display terminal configured to display the document data transmitted by the transmission device via the server, wherein
• the transmission device includes
• an executor configured to execute a printer driver for generating a first divided data element and a second divided data element by dividing the document data into predetermined units and for generating a first thumbnail image data element in accordance with the generated first divided data element and a second thumbnail image data element in accordance with the generated second divided data element, and
• a communicator configured to
• transmit the first thumbnail image data element to the server,
• after transmitting the first thumbnail image data element, transmit the second thumbnail image data element to the server, and
• after transmitting the first thumbnail image data element, transmit the first divided data element and the second divided data element,
• the server includes
• a memory configured to store the first thumbnail image data element, the second thumbnail image data element, the first divided data element, and the second divided data element that are transmitted by the transmission device, and
• a server communicator configured to
