18 conductor cables are recommended only for dot matrix type printers.
25 conductor cables are recommended for dot matrix and non bitronics type laser
printers & scanners. IEEE 1284 is a new parallel interface type that allows true high speed bi-directional
parallel communication. To take true advantage of this new interface, you must use an IEEE 1284 compliant cable. These new cables use three connector types: "A" (DB25M.)
"B" (Cent 36M), and the new connector "C" (High Density Centronics 36M).
