Print Controller Generating Print Data Causing Print Executing Unit to Perform Printing Operation

A print controller configured to control a print executing unit, the print executing unit having a print head in which L number of first nozzles are arranged in a first direction, L being an integer of 2 or greater, a pitch of first nozzles in the first direction between neighboring two first nozzles of the L number of first nozzles being set to a first predetermined nozzle pitch, the print controller comprising:

• an acquiring unit configured to acquire image data;
• and
• a print data generating unit configured to generate print data based on the image data, the print data generating unit including a first drive control data generating unit configured to generate first drive control data based on the image data as the print data, the first drive control data causing the print executing unit to satisfy the following (a)-(d):
• (a) the print executing unit executes a printing process for a plurality of unit regions by alternately repeating a first unit printing process and a first moving process, the plurality of unit regions being defined in a printing medium and arranged in the first direction, each unit region having a prescribed length in the first direction,
• wherein each first unit printing process includes:
• N number of pass processes for forming dots to form a plurality of lines on one of the plurality of unit regions, N being an integer of 2 or greater, each of the plurality of lines extending in a second direction orthogonal to the first direction and including at least one dot arranged in the second direction, in each of the N number of pass processes the print head moving in the second direction relative to the printing medium to form dots on the printing medium along at least one line of the plurality of lines;
• and
• a second moving process in which the print head moves in the first direction relative to the printing medium within a period of time after ath pass process of the N number of pass processes has been executed and before (a+1)th pass process of the N number of pass processes is executed, a being integer from one to (N−1), a pitch of lines in the first direction between neighboring two lines of the plurality of lines being one N-th of the pitch of first nozzles;
• wherein the print executing unit executes, each time Nth pass processes has been executed in one first unit printing process, the first moving process in which the print head moves in the first direction relative to the printing medium;
• (b) at least one of the L number of first nozzles is unused for forming dots on the printing medium in each of the N number of pass processes;
• (c) combinations of the first nozzles used for forming dots on the printing medium in the N number of pass processes are different from one another;
• and
• (d) a movement distance of the print head relative to the printing medium when the first moving process is executed once is different from a movement distance of the print head relative to the printing medium when the second moving process is executed once.
