| im not 100% sure if the cheaper one will work untill the SC team guys lets us know how the program talks to the clip.
im pretty sure the expensive one will, cause its an auctual pci lpt port.

In modern Notebook PCs the legacy standard parallel port was eliminated.
Notebook PC user has following choices to connect the parallel device using:
Low cost USB to Parallel Adapter cable - Converter Cable.
Low cost PCMCIA Card (true EPP Port) - Koutech IO-CBP220 which is dual USB card with built in USB to Parallel converters.
Both of the above solutions emulate the parallel port only. They are not real parallel ports and provide very limited parallel port functionality.
The USB to parallel converters will not work with applications which require direct access to the parallel port registers: Data acquisition, JTAG programmers, software protection dongles etc. The USB to parallel converter hardware requires special drivers and must be driven by Windows XP or 2000 to support USB over the CardBus.
The EPP PCMCIA Parallel card
(Note that EPP standard was developed in late 80-ties to speed up the parallel port with PCs running at that time at 12 or 16 MHz. With today's Notebook PCs running over 100 times faster the EPP is obsolete and is mainly used for marketing purposes only. The EPP old standard over last 6 years is not any more supported by Microsoft and major PC manufacturers).
And the ultimate solution...
The Trans PC Card - Universal Parallel Port PCMCIA card.
The card we offer here is a real parallel port, mapped to the standard port I/O ad*******. It is driven by Microsft drivers of Windows, so there is no need for additional installation/drivers software. The card shows up in the Device Manger as a parallel port LPT1, LPT2 or LPT3. Therefore it is compatible with all parallel devices which can be driven by the fixed parallel ports of desktop PCs. The card may be used in DOS with provided card enabler or with Linux operating systems.
