5. Thermal Printer Head
Thermal head comprises a thermal device and thermal head driver that drives and controls
the thermal device. Data input coming from SI terminal is “High” for printing and “Low” for
not printing. The data coming from SI terminal are transmitted to the shift registers at the
rising edge of the CLK signal.
After transmitting one line data, nLAT signal becomes “Low” and data are transferred to
the latch registers. STB signal becomes “High” depending on the stored printing data and
thermal device is activated.
Division printing of 6block with 64 dots each is supported.
Division printing can reduce the peak current.
