These signals respectively represent the parallel data
from the first bit to the eighth. "1" means high level,
while "0" in logic means low level.
Acknowledge pulse, Low level means that printer is
ready to receive data.
High level means printer is too busy to receive data.
High level means that paper is out.
"High" level is pulled up by resistor.
Low level means the printer is in error status.
