Description

Interaction method and storage medium of multi-service sharing self-service terminal based on mobile application Technical Field The application relates to the field of self-service printers, in particular to a multi-service sharing self-service terminal based on mobile application, an interaction method and a storage medium. Background With the wide spread of mobile internet and non-driven printing technologies, such as local area network discovery and printing based on the IPP protocol, users can conveniently submit print jobs from mobile terminals and complete the process of picking up a piece in public or semi-public scenes, such as offices, word shops and self-service terminals of libraries. In order to solve the risks of misfetching of output objects and information leakage in public environments, the existing system commonly adopts a "secure release Printing" or "Pull Printing" paradigm. In this paradigm, the user's print job is not immediately output, but hovers first in the to-be-released queue of the cloud or local server, and the terminal begins to execute the print job or physically release the finished product that has been pre-printed and temporarily stored in the lock container only when the user personally approaches the printing apparatus and passes identity authentication, such as card swiping, PIN code entry, code scanning, or biometric identification. In order to optimize the user experience of the core flow, the prior art introduces a plurality of auxiliary authentication and release mechanisms, such as authentication realized by two-dimension codes on a user mobile terminal, near field communication NFC or Bluetooth low energy BLE technology, support the user to remotely trigger a release instruction through mobile terminal application, and even realize touch-free release through automatic perception of user identity. On the physical management side of the output objects, the prior proposal mainly comprises the steps of providing a plurality of output sub-boxes for equipment to realize the operation split-flow, or automatically transferring the printed finished products to an independent storage grid with an electronic lock so as to improve the safety and the privacy of the object taking. However, although the above prior art solution contributes to the improvement of security to some extent, its core still follows the basic sequence of "arrival authentication is only started to print or physically release", and takes "public paper outlet" or "box/locker" as the safe picking boundary of the core. The inherent paradigm brings about significant and difficult technical contradiction and limitation while improving the safety, and firstly, the waiting in the presence is unavoidable, and the user experience has a bottleneck. Whether the user operates directly at the device end or remotely through the mobile phone, the user must go through an unavoidable waiting process from successful authentication to completion of printing or opening of the physical cabinet door. This process time consumption grows linearly with increasing number of pages of the document, and a very simple user experience of "get-to-get" cannot be achieved, which is particularly problematic when multiple people are queuing to get a piece during peak hours. Second, the contradiction between pre-printing and privacy protection is difficult to reconcile. If the job is pre-printed to a common tray or unlocked common bin for user waiting time compression, the document content may be completely exposed, with serious risk of disclosure. Even if the box division scheme is adopted, during a multi-operation peak period, mishandling and mistaking can still be caused by no physical locking and isolation and only depending on visual resolution of a user, so that the safety cannot be fundamentally ensured. Third, high security physical isolation schemes are costly and complex. The adoption of the locking cabinet or the independent picking cabinet can effectively improve the safety, but requires additional physical space, power supply wiring, network connection and mechanical maintenance, and complex system docking and protocol development with a print engine, so that the overall deployment cost and the implementation complexity are increased sharply. In addition, most of printing paper paths, man-machine interaction interfaces and locker systems in the existing schemes are designed in a split mode, the coupling degree of the printing paper paths, the man-machine interaction interfaces and the locker systems in system time sequence control and job scheduling is insufficient, and efficient and smooth integrated operation is difficult to achieve. Therefore, the prior art lacks a technical solution capable of fundamentally solving the contradiction, namely, the absolute safety of the output from the content to the physics can be ensured on the premise of not needing to wait for the printing process when the user arrives at the scene and not
