PRINTING APPARATUS AND PRINTING CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To carry out confidential printing of a short waiting time and a high confidentiality by efficiently using a limited storage region.

SOLUTION: When a control part 11 receives at a time point T1 printing data to which attribute data including an output estimated time point and a confidential number are added, only the attribute data is stored at the time point T1. Transmission of the printing data is requested to a computer as a transmitter of the printing data at a transmission requested time point T2 set on the basis of the output estimated time point T3 included in the attribute data. The printing data is held in a printing data storage part 13 for only a time zone from the time point T2 to a deletion time point T4 similarly set on the basis of the output estimated time point T3. The apparatus is configured so that printing based on the printing data is carried out on the basis of the comparison result between a confidential number inputted by an input operation of the user from an input part 10 and the confidential number included in the attribute data.
