ABSTRACT:
A plurality of recording engines, each including an ink jet recording head mounted on a carriage, which ejects an ink droplet onto a recording sheet to perform printing are arranged such that recording sheets are feedable via different feeding paths. Ink is supplied from a main tank common to the respective recording engines. A controller compares an amount of an externally provided print data with an amount of a reference data. The controller divides the print data into data sets, each corresponding to a predetermined amount of page, and provides the data sets to the plural recording engines, when the print data amount exceeds the reference data amount. The controller operates a single recording engine when the print data amount is less than the reference data amount.
