I'm stealing this explanation Tom. Good job!

I am not sure of the context in which you expect an answer. So, let me put
it this way:

The engineers who developed the Panasonic XK 2123 printer designed it for
a particular set of hardware which was described by a well-formulated,
well-described specification. It was designed to connect to a(n IBM-type)
PC using a particular connector and using a protocol which is covered by
the IEEE 1284 specification. It is often referred to as a Centronics port,
particularly in older literature. From this follows the suggestion to
install a card with a parallel port in your computer if it now does not
have one. Also, from this follows the suggestion to set the BIOS in the
computer to SPP. This is what the printer was engineered to use.

If you use a USB to parallel converter, it might work without any problem
if you are sure to select a device that is designed to provide output as
for a device expecting IEEE 1284-specified communication. Not all of them
do. It is not always east to determine which of the available devices meet
this requirement. It is not always plainly stated in the product
description. Sometimes you have to 'dig deeper' to get the specification
documentation for the device.

Since the option to install a parallel port card is almost always present
for desktop units, it is the preferred option. Since it is rarely possible
to install such a device on a laptop/notebook/netbook that lacks a
parallel port, either a cardbus to parallel or USB to parallel provide the
only options.

Since we are on the topic: I would also suggest that you use a parallel
printer cable of high quality that is IEEE A certified, not just IEEE
compliant. The possible issues here are the provision of appropriate cable
conductors/connections for full bi-directional support and signal quality
including cross-talk rejection.

I guess my question is what's the difference in parallel to parallel to
USB parallel
