Printing control apparatus and printing control method

A printing control apparatus configured to use a recording head where a plurality of nozzles are arranged in a row formation with a predetermined pitch, and configured to perform interlace printing on an outward path and a return path such that a resolution is equal to or more than a resolution that is based on the pitch when printing is performed due to supplying of ink being received from an ink cartridge and ink droplets being discharged from each of the nozzles, the printing control apparatus comprising:

• a dischargeable amount acquiring section configured to determine a dischargeable amount per one pass according to a remaining amount of ink in the ink cartridge;
• and
• a split printing control section configured to split a predetermined region in one band an odd number of times according to the dischargeable amount per one pass by splitting the plurality of nozzles into an odd number of groups of nozzles with each group of nozzles including adjacent nozzles, and configured to carry out interlace printing in each of split regions on the outward path and the return path.
