Abstract

An image formation system includes: an encoded image generation device including a first processor that generates print data from manuscript data, sets security information for controlling a print mode of the print data, and generates an encoded image from the print data and the security information; and an image formation device including a second processor that inputs the encoded image, decodes the print data and the security data from the input encoded image, determines whether an output of the decoded print data is available in accordance with the decoded security information, and outputs the decoded print data when it is determined that the output of the print data is available.

First claim

What is claimed is:

1. An image formation system comprising:
an encoded image generation device including a first processor that performs:
generating print data from manuscript data;
setting security information for controlling a print mode of the print data; and
generating an encoded image from the print data and the security information; and

an image formation device including a second processor that performs:
inputting the encoded image;
decoding the print data and the security information from the input encoded image;
determining whether an output of the decoded print data is available in accordance with the decoded security information; and
outputting the decoded print data when it is determined that the output of the print data is available,

wherein:
the security information includes manuscript identification information that identifies the manuscript data, and number-of-times-of-printing threshold information that sets a threshold of a number of times of printing of the manuscript data, and
the second processor performs:
recording print history information including the manuscript identification information included in the decoded security information and information relating to an accumulated number of outputs of the decoded print data, every time the decoded print data is output; and
determining that the output of the print data is available, when the print history information that corresponds to the manuscript identification information included in the decoded security information has not been recorded, or when the print history information that corresponds to the manuscript identification information has been recorded, and the information relating to the accumulated number of outputs included in the print history information is compared with the number-of-times-of-printing threshold information included in the decoded security information so as to find out that printing is available.

2. The image formation system according to claim 1 , wherein
the security information includes image formation device identification information for identifying the image formation device, and
the second processor determines that the output of the print data is available when the image formation device identification information included in the decoded security information indicates a local device.
