SYMPTOMS
========

If you have two or more parallel ports using the same IRQ and you copy files
directly to the printer port(s) from a command prompt using the Copy command,
the file may not be directed to the correct port (printer). Note this happens
when you use the Copy command locally or to its shared networked printers.

RESOLUTION
==========

To work around this problem, put the LPT ports on unique IRQs.

MORE INFORMATION
================

Steps to Reproduce Problem
--------------------------

On a computer with two or more printer ports installed on the same IRQ (usually
7), do the following:

1. Open a command prompt or CMD.

2. Copy a file using the following command:

  Copy C:\WINNT\SYSTEM32\CONFIG.NT LPT1:

The print job will go to the default printer regardless which port you copy the
file to.

NOTE: This problem only occurs when you are using the Copy command to port
commands.
