As the first step, you should try to avoid the special Driver 
and use the Parallelport-Driver from Windows.
The default Location in the ObjectManager for
the first Parallel Port is: "\Device\Parallel0".
(HKLM\Hardware\Devicemap\Parallel Ports\")

But Parallel Ports are unsupported in wine yet....
(For serial Ports, the Driver is: "dlls\ntdll\serial.c")

You need to use the Windows-API for the access:
CreateFile / ReadFile / WriteFile and DeviceIOControl.

I do not know, if this need Admin-Rights...
