7.2 Interfaces

Parallel interface, serial interface and USB interface are the standard interfaces for the printer.
The interface pin assignment is listed below. (The signal with overline indicates low true logic level.）

7.2.1 Parallel interface

Parallel interface pin assignment
STROBE ¯¯¯¯¯¯¯¯¯
Normally synchronous input signal is used to prompt that the data is sending to the port. Normal state
is high logic level, while low logic level indicates DATA1～DATA8 will read the current data. The minimum
pulse width is 0.5 microsecond.
DATA1~DATA8
Signals to receive data sent from host. Logic 1 is high level and the minimum pulse width is 1.5
microseconds. DATA1 is least significant bit while DATA8 is most significant bit.
ACK ¯¯¯
Signal to request sending data from host. ACK acts as the output signal when the printer is ready for
receiving new data after previous data is read and saved in DATA 1～DATA8. Normal state is high logic
level. After activating, it turns to low logic level. The pulse width is about 4 microseconds.
