ABSTRACT:
During the creation of print job data on a job creation terminal, a flushing pattern placement reservation region is previously arbitrary specified and described in placement condition data. Flushing pattern data is previously stored in a storage part. A flushing judgment part specifies frequency with which ink is ejected from each nozzle of a printing apparatus from rasterized data, to judge whether a flushing operation is needed or not. When the flushing operation is needed, a printing execution instruction part acquires the flushing pattern data for causing the ink ejected from a target nozzle to form a certain flushing pattern, to combine the flushing pattern data with the rasterized data, and the printing apparatus executes printing based on the resultant data obtained by the combination. This achieves the production of a printed material while ensuring the flushing operation.
