Abstract

The invention discloses a remote printing method and device based on websocket and electronic equipment. The method comprises the steps: determining whether self-defined protocol verification is passed or not, if so, establishing a long connection between a printing terminal and a websocket cloud service, obtaining to-be-printed data and adding the same into a cache; detecting whether to-be-printed data is contained in the cache in real time, if so, sending the to-be-printed data to the websocket cloud service, and pushing the to-be-printed data to the printing terminal for printing through the websocket cloud service. According to the technical scheme provided by the invention, the receipt printing by manually operating a computer in the prior art is replaced by automatic remote receipt printing through websocket cloud service, so that the picking efficiency of a picker is improved, the printing error rate is reduced, and the problems of long time, low picking efficiency and high error rate in the receipt printing by manually operating the computer in the prior art are solved.

Description

technical field [0001] The invention relates to the field of remote printing, in particular to a websocket-based remote printing method, device and electronic equipment. Background technique [0002] After the user purchases medicines through the Internet, the pharmacy will select the purchased medicines by the picker according to the user's purchase information, and print out the receipts containing the product information and the receipts containing the user's contact information. In the actual drug picking scene of the pharmacy, the picker first picks the medicine through the mobile phone, and then goes to the computer to operate on the computer to print the documents required for the delivery of the medicine. [0003] However, in the whole process, the picker needs to pick the medicine on the mobile phone first and then print the document on the computer. This method of manually operating the computer to print the document takes a long time, which reduces the picking eff...
