(e) Interface signals

     *STROBE (from host to printer)
     DATA 1-8 signals are read into the printer by this signal.
     The normal condition is "High" and the valid signal is "Low" pulse.
     The pulse width needs to be longer that 1 micro second.
     
     DATA 1-8 (from host to printer)
     8-bit parallel input data.
     DATA 1 is LSB and DATA 8 is MSB.
     These signals are normally "Low" level.
     Data "1" is "High" level and data "0" is "Low" level.
