The first thing I would do is resolve the conflict with your IDE controllers.
Check System properties for a Dos compatibility mode problem.
(Right-click My Computer, select properties, then Performance tab)
This can become very involved, so I advise you to read and understand the following before attempting any changes.

Next, I think you must have an Enhanced (ECP) port enabled for bi-directional printing.  This will require an IRQ and DMA.

Let me know how it goes.

What IRQ is it trying to assign to your LPT Port?

Is it trying to assign the printer pprt to IRQ 15?

What kind of Motherboard do you have? ( I Just dealt with a similar problem on a Biostar Pentium MoBoard).

Let me know.
ptm - what sort of computer?  486?  Pentium?
