technical field

The invention belongs to the technical field of self-service cloud printing control, and in particular relates to a file mechanical storage system based on cloud printing.

Background technique

With the mass production and scattered placement and operation of cloud self-service printers, the offline pick-up method of network transmission files effectively prevents the spread of computer viruses caused by physical connections and relieves people's printing pressure. However, its inherent print-and-take attribute is difficult to avoid a series of problems such as work delays caused by crowds gathering and long waiting times during the printing peak period.

In order to solve the above problems, realize remote instant uploading and printing of files, and take them offline at a convenient time, the present invention designs a cloud printing file mechanical storage system. Combined with the existing cloud printing technology, the system can automatically store the printed paper documents, and inform the user of the relevant storage information in time, and pick up the documents when it is convenient for the user. In addition, the system can also destroy the discarded documents caused by printing failures, and at the same time activate the backup printer to continue the operation. The storage system is based on cloud printing technology, which can give full play to the advantages of remote printing and reasonably solve the problem of cloud printing file disposal.
