SRP-F310/312
4-3-9 Thermal Printer Head Circuit
First, the CPU sends a Serial Clock and Serial Data 256bits(32Bytes) to the Shift Register of the Thermal
Printer. The Serial Data are stored to each Shift Register in the Thermal Printer. Because the Data#1 Pin and
the Data#2 pin are shorted on Main PCB, the Data(256bits) are stored in both Shift Register#1 and #2.
Second, the CPU send a Latch Signal to the Thermal Printer. Then, the Data of both Shift Register#1 and #2
(256*2=512bits) are moved to the Latch Register. After that, the CPU sends a Strobe Signal to the Thermal
Printer. Then, the Printer outputs the Serial Data. Each Strobe Signal manages the Printer Dot.
