Description
A low strobe pulse to read data into the printer. The
pulse width is greater than 0.5 microseconds.
These signals represent information of the first to
eighth bits of parallel data. Each signal is at high
level when the data is logic 1 and low when it is
logic 0.
A low pulse from the printer signals the control that
the printer is ready for additional data.
A high level indicates that the printer is busy.
A high level indicates that the printer is out of paper.
A low level indicates the printer is offline or in an
error condition.
