The original IBM-PC's Parallel Printer Port had a total of
<font color="#0000ff">12 digital outputs</font>
and
<font color="#ff0000">5 digital inputs</font>
accessed via 3 consecutive 8-bit ports in the processor's I/O space.
</p><ul>
<li><font color="#0000ff">8 output pins accessed via the <b>DATA Port</b></font>
</li><li><font color="#ff0000">5 input pins (one inverted) accessed via the <b>STATUS Port</b></font>
</li><li><font color="#0000ff">4 output pins (three inverted) accessed via the <b>CONTROL Port</b></font>
</li><li><font color="#00a000">The remaining 8 pins are grounded</font>
</li></ul>
