This invention has as its object to provide an image processing apparatus and method which can reliably and appropriately insert a page break by a simple process. To accomplish this, it is checked if the number of lines transferred to a printer is smaller than a page break reference line count N. N is a value equal to or smaller than a value obtained by subtracting the number of vertical dots of a maximum font that a browse task can rasterize from a maximum recordable line count Max. When data for the page break reference line count N or more have been transferred to the printer, it is checked if data of the transferred line has the same color. If the data for one line have the same color, it can be determined that the line does not contain any character (the spacing between neighboring lines). Hence, if a page break is inserted at that line, characters can be prevented from being printed across two pages.
