Block chain based printer and realization method

The invention belongs to the technical field of block chains and proposes a realization method for a block chain based printer. The method comprises the steps of receiving a sent printing file and embedding information of the printing file into a block chain. The block chain based printer comprises a printing file information recording module and a block chain client module, wherein the block chain client module comprises a block chain IPC interface; the printing file information recording module is used for collecting the information of the printing file and sending the information of the printing file to the block chain client module; and the block chain client module is used for embedding the information of the printing file into the block chain through the block chain IPC interface. With the adoption of the block chain based printer and the realization method, a printing management mode in an enterprise is established, and the leakage of enterprise internal confidential information and the falsification and replacement of the file are confirmed, so that the enterprise loss is made up for.
