1.2 Print Drive Method

To print, the printer ejects ink from ink nozzles. To this end, 16-bit serial data is
transferred once as a latch signal to each nozzle array (total of 8 arrays: black
even/odd-number array, cyan, magenta, yellow/even/odd-number array). This
operation is repetitive.
The 16-bit serial data includes the following: Data (DATA0 ~ 9) that decides whether or
not to heat 10 nozzles, data (BE0 ~ 4) that decides which nozzles to heat, and the
dummy heater signal.
