A com port is a communications port. It could be a serial port or a parallel port. To see what com ports are equipped, right-click on "my computer", click properties, click the "device manager" tab and click the + in front of "ports".

Mr. Chicken: You wrote that a Com port is the serial OR the parallel port and that is a misconception.

The Com port is a serial connection designed for two way communication. Whereas the Parallel port was designed as a one way port with limited two way handshaking.

Parallel is faster, moving a full byte (8 bits) at a time with handshaking on a different wire.
Serial moves one bit at a time and this includes an extra stop bit plus checksum bits. Handshaking takes place on separate wires.

I recently had my printer on parallel but needed that port so I switched it to USB. BIG slowdown! The slowdown is in the initial feed to the printer, once it starts printing there is no noticeable difference. Since print speed is not of a concern, and I am talking about ten seconds or so, I am content to leave it alone.

To the original post, Skull is correct, it is a DB9 male connection - 9 pins on the PC, 9 holes on the device plug.

If needed, you can get a serial-to-USB converter.
