Printing apparatus, controlling method and computer program

摘要

A printing apparatus is provided which can utilize a power supply to its maximum capacity without overly degrading a throughput. Print area that can be printed in one scan of a print head is divided into a plurality of blocks. The number of data indicating print in each block is detected. Then the detected value is compared with a plurality of thresholds. Based on a result of the comparison, a scan speed of the print head and the number of scan are determined. This arrangement allows for a selection of an optimum printing method from among a plurality of scan speeds and a plurality of divided printing modes even when an image that may cause a current in excess of the maximum power supply capacity to flow is printed. With this printing apparatus it is possible to execute printing fully utilizing the power supply capacity without overly degrading the throughput.
