Printing apparatus, printing method, and non-transitory and computer-readable medium storing computer program

A printing method executable in a printing apparatus including a main controlling circuit, a sub-controlling circuit group including a plurality of g-th sub-controlling circuit and a h-th sub-controlling circuit downstream of the g-th sub-controlling circuit which are connected in series and which are configured to transfer print data transmitted thereto by the main controlling circuit from the g-th sub-controlling circuit to the h-th sub-controlling circuit, and a plurality of heads each of which is driven by one of the plurality of sub-controlling circuits corresponding thereto,

• the print data including data of a plurality of pixels,
• the printing method comprising:
• causing the main controlling circuit to execute:
• generation of, based on the print data, data of a first pixel group to data of an n-th pixel group regarding, respectively, the first pixel group to the n-th pixel group each including pixels which are not adjacent (the “n” representing a natural number which is 2 or more);
• and
• transmission of the data of the first pixel group to the data of the n-th pixel group to the sub-controlling circuit group;
• and
• causing each of the plurality of sub-controlling circuits to execute:
• obtainment of data of pixels, of the plurality of pixels, which are associated with each of the plurality of sub-controlling circuits, from the data of the first pixel group to the data of the n-th pixel group;
• and
• driving of one of the plurality of heads corresponding thereto, based on data of the pixels associated with each of the plurality of sub-controlling circuits, wherein
• the data of the first pixel group to the data of the n-th pixel group include data of a h-th pixel group associated with the h-th sub-controlling circuit, and
• in a case where an abnormality occurs in the data of the h-th pixel group transmitted from the g-th sub-controlling circuit to the h-th sub-controlling circuit, the q-th sub-controlling circuit is configured to execute re-transmission of the data of the h-th pixel group to the h-th sub-controlling circuit.
