Is there a way for Purebasic to control a Parallel device, the same way I have seen it control a Serial connected device?

I don't yet have a Parallel to USB transceiver adaptor yet, but might get one if there is enough control.

I have used USB/Serial Transcievers with no problems (after a fight with the code of course).

For example, I have an old printer. It has a Centronics connector on the back, that is equatable to PC parallel. I have been able to control it via Serial and the correct conversion cable. I know exactly which numbers it should receive in a sequence, but have not thought about attempting this in Parallel before.

It is possible to access the registers directly, but ...

you need a kernel driver for this, because MS decided that only a ring0 kernel driver has the privilege to access ports directly.
There are some of them available.

I guess it should work the way you used to work with LPT ports with the InpOut32 DLL from infratec's post, if the USB adapters are not completely proprietary:
