Abstract: An image printing system, and a printing method according to the selection of either whole printing or partitioned printing, are provided. The image printing system includes a printer driver installed in a computer and a printer controller installed in a printer connected to the computer. The printer driver provides a print option menu on a screen of a display device to allow a user to select either whole printing or partitioned printing on a print object manuscript file to be printed, and outputs the selected result information to the printer together with a print data file transformed into a printer language with respect to the manuscript file. The printer controller reads data transmitted from the computer via a communications interface and determining a print sequence by a printer engine so that the total pages of a print data file selected to be printed by partitioned printing are divided and printed in segments at intervals of a set period in units of a determined number of pages.
