Abstract

Provided is an image forming system for pull printing that does not require a server and does not require input of keys or the like at the time of output. A division part divides pull print document data into a plurality of blocks including a critical block that includes information required for printing and transfer blocks that include other information. A storing and transmitting part transmits the transfer blocks of the blocks to at least two of preserving apparatuses. A critical block acquisition part acquires the critical block. A transfer block acquisition part acquires each of the transfer blocks of the document data corresponding to the critical block from any of the preserving apparatuses. A document reproduction part collectively reproduces the critical block and each of the transfer blocks into the document data.

Dependent claims

An image forming system capable of pull printing and including a transmitting apparatus, a preserving apparatus and an output apparatus, wherein

the transmitting apparatus comprises:
a division part configured to divide pull print document data into a plurality of blocks including a critical block that includes information required for printing and transfer blocks that include other information;
and configured to create a blockchain of document data by sequentially calculating and including a previous hash value of a previous block;
and
a storing and transmitting part configured to transmit the transfer blocks of the blocks divided by the division part to at least two of the preserving apparatuses;
and
the preserving apparatus comprises:
a storing part configured to store the transfer blocks received from the transmitting apparatus;
an outputting and transmitting part configured to transmits the transfer blocks stored in the storing part according to an instruction from the output apparatus;
the output apparatus comprises:
a critical block acquisition part configured to acquire the critical block;
a transfer block acquisition part configured to acquire each of the transfer blocks of the document data corresponding to the critical block acquired by the critical block acquisition part from any of the preserving apparatuses;
a document reproduction part configured to collectively reproduce the critical block and each of the transfer blocks acquired by the transfer block acquisition part into the document data;
and
an image forming part configured to output document data reproduced by the document reproduction part.
