The invention provides a cloud printing method with real-time deduction of copying and scanning fees, comprising the steps: scanning, by a mobile device, a quick response code displayed by a printer;correlating, by a gateway, a user to the printer temporarily; detecting, by a cloud server, whether the printer enables copying permission or scanning permission; detecting, by the cloud server, whether the amount in a user's local account is enough to pay the fee for single copying or scanning; if yes, opening, by the gateway, the copying or scanning function; if not, ending the process; executing, by the printer, copying or scanning operation once; uploading, by the gateway, the record to the cloud server; deducting, by the cloud server, the fee for the copying or scanning in real time; circularly detecting the amount in the local account, executing operations, and deducting fees to end the process until tasks are done. The method of the invention has the advantages that fees are deducted in real time during execution of copying or scanning operation, the technical problem of the cloud server in calculating copying and scanning fees is solved, and the technical problem in deducting fees for copying and scanning operations is also solved.
