What is the difference between an IEEE-1284 cable and a standard one?

What is the difference between an IEEE-1284 cable and a standard one?
This is often a misunderstood concept. First, let's make the
distinction between bidirectional and 1284-compliant cables. Applying
the 1284 standard to cables, the IEEE-compliance primarily means
speed, and these cables are precisely manufactured for that purpose.
The 1284 standard sets exacting specifications on cable impedance,
shielding, length, and connector styles to insure that they will be
up to the task. Bidirectional cables must simply be able to transfer
data in both directions, and your everyday 25-wire printer cables
(and all straight-thru 25 wire cables) are capable of this; they are
not, however, capable of the speed required by 1284-compliant
peripherals. Peripherals which are IEEE-1284 compliant (such as many
newer printers) require the use of a high-speed cable, as do most of
the devices that connect to an EPP or ECP
