Can't keep Printer Port Data Bits High.

I'm using a self designed module to provide an interrupt to the printer port (ack signal). The module uses the data bits to power it. The problem is I can't keep the data bits set high. They all seem to go low after a while and stay low until a reboot. I have the Printer Port set to Normal mode which I believe is SPP. We are also setting the port to output FF once a Frame (60 hz). Is there a trick to getting the Data Bits to remain high at all times? We are using XP.

Thanks
Mike
