Abstract

There is provided a data output apparatus, data output method, program, and storage medium which preferably execute a printing process using print data input to the printing apparatus via an external storage device without decreasing the speed of the printing process while ensuring a security of classified information contained in the print data. Print data stored in a detachable external storage device such as a removable medium is input, and then the print data is developed to image data printable by the printing apparatus. The developed image data is printed out on a printing medium. Upon the development process of the print data to the image data, the development process is executed while switching the first mode to execute the development process using a storage area of the external storage device and the second mode to execute the development process using a storage area of the printing apparatus.

Dependent claims

A data output device comprising:

an input unit adapted to be capable of inputting at least data of a specific storage unit;
an output unit adapted to output an input data;
a storage unit different from said specific storage unit;
a controller adapted to generate data to be output by said output unit using a storage area of said specific storage unit when output of data of said specific storage unit is executed by said output unit, to execute, using a storage area of said specific storage unit, a first generation process for, of data of said specific storage unit, data of a part which requires high security, and to execute a second generation process for data of a remaining part of data of said specific storage unit using a storage area of said storage unit;
and
a selector adapted to select any one of a mode to store both data generated by the first generation process and data generated by the second generation process in said specific storage unit, a mode to store only data generated by the first generation process in said specific storage unit, and a mode to delete both data generated by the first generation process and data generated by the second generation process.
