Printing apparatus, data transmitting method and medium

A data transmitting method executed by a printing apparatus,

• the printing apparatus including:
• a main control circuit;
• a sub-control circuit group connected to the main control circuit in series, the sub-control circuit group being configured to transfer image data from the main control circuit downstream;
• and
• a head group configured to be driven by the sub-control circuit group, wherein:
• the sub-control circuit group has at least two sub-control circuits including a second sub-control circuit and a first sub-control circuit connected to the second sub-control circuit at an upstream of the second sub-control circuit;
• and
• the image data includes second image data and first image data, the method comprising:
• transmitting the second image data to the second sub-control circuit by the main control circuit;
• and
• transmitting the first image data to the first sub-control circuit by the main control circuit, after the transmitting of the second image data.

A non-transitory computer-readable medium storing a program that is executable by a printing apparatus,

• the printing apparatus including:
• a main control circuit;
• a sub-control circuit group connected to the main control circuit in series, the sub-control circuit group being configured to transfer image data from the main control circuit downstream;
• and
• a head group configured to be driven by the sub-control circuit group, wherein:
• the sub-control circuit group has at least two sub-control circuits including a second sub-control circuit and a first sub-control circuit connected to the second sub-control circuit at an upstream of the second sub-control circuit;
• and
• the image data includes second image data and first image data, the program is configured to cause the main control circuit to execute a process of:
• transmitting the second image data to the second sub-control circuit;
• and
• transmitting the first image data to the first sub-control circuit after the transmitting of the second image data.
