InpOut32.dll is a workaround that allows you to access the standard parallel port hardware address thru some versions of Windows operating systems. As such, it probably would be useless on these USB-Parallel devices. Your only hope would be if you could get the manufacturers specs and access to their drivers code. If you can get this info, it may be possible to re-write your aps to use it like a standard parallel port, but getting there thru their device driver software.
