Function
Signal for sending data to printer.
Steady-state value is High. Printer
reads data until this signal becomes
from Low to High.
Input signal for receiving 8-bit data.
Logic 1 is High. DATA0 is
LSB and DATA 7 is MSB.
Signal indicating that printer has
read data into device completely.
This signal is output in response to
/STB.
Signal indicating that printer is
unable to receive data. Printer is
able to receive data when this signal
is Low.
Signal indicating Paper Out of
printer. This signal is Low when
paper is loaded and is High when
paper is out.
Signal indicating that printer is under
online status. Printer is capable of
receiving data when this signal is
High.
Signal used for bidirectional
communication
Ground
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.
Signal for initializing printer. Steady-
state value is High. Printer is
initialized by Low.
Signal indicating that printer is faulty.
