In a printing apparatus of the present invention, image data divided into a plurality of pages and supplied from an application program are printed on a roll of machine glazed paper without any margins set between adjoining pages. This arrangement enables a large image to be printed on a large-sized printing medium, such as a banner. A printer driver in the printing apparatus sets feeding amounts of sub-scan according to a selected printing mode. In the case where a standard printing mode is selected, the printer driver sets the feeding amounts to execute an upper end process and a lower end process with regard to each page. In the case where a continuous printing mode is selected, on the other hand, the printer driver maintains a periodic variation of standard feeding amount, except the upper end process carried out in a first page. When a print head is located across a boundary between adjoining pages in the course of printing in the continuous printing mode, print data with regard to the adjoining two pages across the boundary are output to the respective nozzles, and specific areas immediately before and after the boundary are recorded simultaneously by one pass of the main scan. This arrangement of the present invention effectively prevents banding from occurring in the vicinity of the boundary.
