<P>PROBLEM TO BE SOLVED: To prevent the leakage of the contents of the picture data by a simple processing, when transmitting picture data from a controller to a printer. <P>SOLUTION: The controller of the image processor comprises a sequencing processing portion 41 for so decomposing picture data into predetermined memory unit groups as to sequence in a predetermined way the memory units, a print-data generating portion 42 for so describing print controlling information and the picture data by a page description language and so integrating picture-data sequencing information into the print controlling information as to generate print data, and a first communicating portion 34 for transmitting the print data to a printer in an order of the print controlling information and the image data. The printer has a second communicating portion 51 for receiving the print data in the same order, a second picture processing portion 6 having a restoring portion 62 for restoring the picture data present in a sequenced state to the original state thereof and having a sequencing-pattern memorizing portion 63 for memorizing a plurality of sequencing patterns, and a printing portion 53. The restoring portion 62 so collates the sequencing patterns memorized in the sequencing-pattern memorizing portion 63 with the sequencing information included in the print data as to restore the picture data. <P>COPYRIGHT: (C)2009,JPO&INPIT |
