The information in this article applies to:
With machines with more than one parallel port, all printing attempts to ports other than LPT1 results in the output always going to LPT1.
Microsoft has confirmed this to be a problem in Windows NT. We are researching this problem and will post new information here as it becomes available.
1. Configure a machine with two or more line printer ports (LPT1, LPT2) and
   attach a printer to each port.
3. Issue the command: "copy <text file> LPT1:". This will print
   successfully to LPT1.
   as expected; it will instead print to LPT1.
