In an inkjet printing apparatus having a plurality of printing modes (Table 1) with different scanning speeds, first and second preliminary discharge performing positions (225, 226a) are provided within the moving area of a carriage (216) as positions where preliminary discharge is performed to cause a printhead to discharge ink irrespective of printing, and a position or a combination of positions where preliminary discharge is performed is set from the first and second preliminary discharge performing positions (225, 226a) in accordance with the scanning speed in a set printing mode (FIG. 4). This makes it possible to execute preliminary discharge at intervals within necessary intervals even if the scanning speed is decreased when high resolution printing is performed. |
