SYMPTOMS
When you copy a text document to an LPT port at a command prompt, you may receive the following error message:

All pipe instances are busy.

Starting a new command prompt yields the same error message.

RESOLUTION
To resolve this issue, restart the spooler. To do so, type the following commands at a command prompt:

net stop spooler

net start spooler

Or, restart the Spooler service using the Services snap-in.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
