发明名称 Printing apparatus and power supply load reduction method for printing apparatus
摘要 In a printing apparatus having a plurality of full-line print heads each having a print element array corresponding to the width of a print medium, upon receiving print data that uses a plurality of print media, a print duty, which is the ratio of the number of nozzles used in a print process to the total number of nozzles, is computed as a numerical value that pertains to electric power to be supplied to the print heads upon printing that print data. When the computed value is larger than a predetermined value that represents electric power which can be supplied from a power supply of the printing apparatus, the distance between the plurality of print media is increased so that the numerical value that pertains to the electric power becomes equal to or smaller than the predetermined value. With this control, deterioration of image quality and extreme drop of the printing speed can be prevented without unwantedly increasing the power supply capacity.
