Abstract: A cloud printing method and a cloud printing system includes: sending a print request to a first server when a file is clicked at first application of a client to execute printing; determining whether a target printer supports printing the file; transmitting the file to the target printer to execute printout of the file based on that the target printer supports printing the file; transmitting the file to a printer manufacturer server or to a second application based on that the target printer does not support printing the file; converting a data format of the file into a data format supported by the target printer to generate a print job; sending the print request to the target printer, and transmitting the print job to the target printer to execute printout of the print job.

Abstract: A cloud printing method includes in response to a click on a file in an application program of a client terminal to execute printing, receiving, by a cloud server, a print request sent by the client terminal, generating, by the cloud server, a print job and a uniform resource locator (URL) of the print job based on the print request, and starting, by the cloud server, a print microservice and publishing a print task to a message queuing telemetry transport (MQTT) microservice according to the print job. After a printer is connected to the cloud server, the printer is configured to send a print subscription request to the cloud server. The MQTT microservice is configured to send the print task with the URL of the print job to the printer. The printer is further configured to download the print job from the cloud server based on the URL of the print job and print the print job.
