What does a parallel cable look like?
There are two types, a 25 pin male to 25 pin female, and the
most common, 25 pin male to a Centronix, which is what printers
use.
There are 25 pin cables that is not are not printer cables, but
they are very uncommon. Almost all the time when someone refers to
a parallel cable they are referring to a printer cable, which is a
25-pin to Centronix cable.
