<p><P>PROBLEM TO BE SOLVED: To secure confidentiality when reusing bit map data made in printing output. <P>SOLUTION: A printer controller 2 receives PDL data from a client PC1 (Step S10), and converts the PDL data into the bit map data (Step S11). When a first password required for confidential printing is set in the received PDL data (YES in Step S12), restricting information (a password) on reuse of the bit map data is generated (Step S13), and its restricting information and the bit map data are associatively preserved in a hard disk 206 (Step S14), and print data is transmitted to a printer 3 (Step S15). <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
