Electronic express sheet printing method, server, system and equipment

Abstract

The invention relates to an electronic express sheet printing method, a server, a system and equipment, and belongs to the technical field of printing. The method comprises the following steps: establishing long connection with a client based on heartbeat of the client; a printing task request is received, the printing data message is cached in a preset database according to the printing task request, and the printing task request carries the printing data message; and receiving a printing task pulling request based on the batch code, pulling the printing data message in a preset database according to the printing task pulling request, sending the printing data message to the client terminal, and sending the unprinted data message to the printing terminal, so that the printing terminal prints the electronic express sheet of the unprinted task. Based on an equipment heartbeat mechanism, a long connection is established between a client and a server, so that a printing instruction and aprinting data packet are accurately transmitted, the timeliness and accuracy of the printing instruction are ensured, and the abnormal conditions of packet loss, instruction pushing delay and the likein electronic express sheet printing of remote equipment are solved.
