Signal functions
Signal name Function
/STB
Signal for sending data to printer.
Steady-state value is High. Printer
reads data until this signal becomes
from Low to High.
DATA0 to
Input signal for receiving 8-bit data.
Data7
Logic 1 is High. DATA0 is
LSB and DATA 7 is MSB.
/ACK
Signal indicating that printer has
read data into device completely.
This signal is output in response to
/STB.
BUSY
Signal indicating that printer is
unable to receive data. Printer is
able to receive data when this signal
is Low.
PE
Signal indicating Paper Out of
printer. This signal is Low when
paper is loaded and is High when
paper is out.
SELECT
Signal indicating that printer is under
online status. Printer is capable of
receiving data when this signal is
High.
/AUTFD
Signal used for bidirectional
communication
GND
Ground
VCC
Signal indicating that the power of
printer is on. This signal allows
verifying ON/OFF status of power of
printer and connection status of
printer cable.
/INT
Signal for initializing printer. Steady-
state value is High. Printer is
initialized by Low.
/FAULT
Signal indicating that printer is faulty.
/SELIN
Signal used for bidirectional
communication
