for Windows 3.1/95/98/98SE/WinMEXP might work with the NT driver created in 1998 there is no XP driver for this interface as far as i know it would be best to avoid this interface
unless you want a midi interface for any of the pre-XP windows versions
or simply to use this as a stand alone patchbay after programming it on a win9x box with the software
https://web.archive.org/web/19970415080756fw_/http://www.midiman.net:80/prportman4x4.htmThis will also function when disconnected from the PC, operating as a stand‑alone MIDI patchbay, using MIDI program changes to select patches. (theres remote control software for windows 3.1?)

Printer Port Hardware Modes
Most computers’ parallel printer ports operate in one or more of
the following modes: Compatible, Bi-directional, EPP, and ECP.
The mode is usually manually set in the CMOS setup of the computer
(please see your computer’s user guide for more information).
While Compatible mode works with almost all printer
ports, it is also the lowest performance. If available, choose ECP
or Bi-directional first. Then when running the diagnostic software
(or drivers), set H/W Mode to match the printer port mode
you’ve selected in your CMOS setup. If the higher performance
settings do not work with your computer, back off to Compatible
Mode, which is adequate for MIDI data rates.
